Sony Betamax tapes

Sony, the inventors and primary supporters of the Betamax format, produced tapes from its earliest days up through the end of the format, with a range of different lengths, designs, and tape qualities.

K series tapes (1975-1977)

The original Sony Betamax tape lineup included the K30 and K60. The maximum recording time of one hour at introduction was comparable to older open reel video formats as well as direct competitors like the Sanyo V-Cord II but became the first nail in the coffin for Betamax when VHS released with a standard tape length of two hours
A darker, less brown variant of the K60. The K series was quickly replaced by the first L series tapes when the standard VHS tape settled on twice the duration of the K60s, prompting Sony to obfuscate running time behind the more impressive sounding tape lengths

L series tapes (1977-1980)

The L series tapes obfuscated Beta's shorter runtimes behind the larger and more familiar "L" length designations.

Japanese market

The first L series tapes came in these subtly striped slipcases, with variations existing for different manufacturing and sales regions. This early Japanese market L500 includes the length of the tape in meters on the front and the original X1 and X2 designations
During the lifetime of the original L series, the range of available tapes expanded to include everything from a 15 minute tape at Beta I speed to five hour tape at Beta III speed. This Japanese market L125 was produced after X1 and X2 were renamed to Beta I and Beta II, but before the introduction of Beta III
Label sheets for these tapes were similar to the K series tapes, with duplicate labels and indexing numbers

The L750 length tape was introduced alongside cheaper Beta II recorders in Japan in late 1977 and in the spring of 1978 in the US. This Japanese example does not include a Beta I runtime and predates the introduction of Beta III

North American market

The K30 tape was replaced by the L250 and the K60 was replaced by the L500
These tapes were introduced in the United States in fall 1977 alongside new VCRs like the SL-8200 that could record in Beta II, then called Betamax X2, with the original Beta speed being retroactively called X1 or simply Betamax

Assembled in USA variant that includes the test recording warning but not the runtime chart
A sealed two pack of assembled in USA L750s



Bilingual made in Japan variant that again drops the runtime chart as well as the recording warning, possibly to avoid having to have them written out in multiple languages



The first L830 tapes were introduced later in this series of tapes alongside new Beta III speed capable VCRs. The new thinner tape stock was not recommended for use in older recorders

Original Dynamicron series (1980-~1982)

The first Dynamicron tapes for the 1980s had a vertical color bar motif. Sony dropped the "Betamax" name from these tapes and started using the more "unified" Beta logo. Before this point, some other manufacturers had different names for their Beta format recorders and cassettes like BetaVision or BetaCord.

Japanese market

Sony introduced the high grade HG tape in this generation - actually, I don't have any regular Japanese issue tapes from this generation, just an HG and a tape explicitly for business use.

American market

Short tapes like this L125 were most commonly used in industrial applications and often recorded in Beta I speed, containing short informational or training recordings. Early examples of Dynamicron tapes do not have the color bar pattern carried over to the back
Early Dynamicron L250 with no rear color bars. The higher-grade HG tapes of this generation also do not carry over their own cool-toned color bar motif to the back of their slipcases
Early American Dynamicron L750 without the rear color bars
The uncommon L165 length Dynamicron, introduced after the color bars were carried over to the back. This length was pretty much only used in industrial and other dubbing applications outside of Japan, and does not appear on the time chart of other lengths
A slightly later made in USA L500 variant with color bars but without the line about Dynamicron being the name of Sony Beta-format videocassettes
Made in USA L500 with color bars and Dynamicron text. These were the first Sony tapes to use more cardboardy sleeves instead of the more plasticized sleeves of the previous generations, although they are still pretty good quality

Made in Japan Dynamicron L830. By this point, Sony was also selling VHS tapes in similarly designed boxes. Several Sony VHS tapes can be seen in the VHS gallery
Generally for institutional use, shorter length tapes continued to be sold by Sony - many manufacturers sold only an L750, or an L500, L750, and L830 lineup

HG and other tapes

This generation also introduced Sony's high-grade HG tapes with cool-toned color bars which did not carry over to the back. Sony produced a few other varieties of tape during this period.

Horizontal Dynamicron series (1982-1985)

The next generations of Dynamicrons rotated the color bars to be horizontal and were used into the mid 1980s.

Japanese "N" series tapes (1982-1983)

Advertised starting by September 1982 and lasting into at least late 1983 was a "New" Dynamicron tape with horizontal stripes. These Japanese-market "N" tapes were sold alongside a range of UX high grade tapes.

Japanese market L250N tape

Labels for these N tapes resemble the labels from Japanese market vertical Dynamicron tapes



L330N Dynamicron



These tapes had thicker horizontal lines than the later horizontal Dynamicrons and lacked the It's a Sony "dots" as well as a UPC and other details on the back

L500N Dynamicron label sheet



The HG high grade tape was replaced with the UX series of tapes for the early horizontal Dynamicron series. The HG would later return in a new flashy silver case later in the horizontal Dynamicron era

Japanese horizontal stripe tapes (1984-1985)

These tapes added the Sony "dots" logo that was included usually as a sticker on their audio and video equipment. The high-grade tape returned to being known as the HG with a new UHG tape also introduced.

Japanese market L330 tape, an uncommon length for blanks

UPC location variant of the USA Dynamicron L750
  I really like the sticker that looks like a small Dynamicron tape box
The UHG Ultra High Grade tapes turned out to be prone to dropouts, the streaky white lines sometimes seen when the tape heads cannot pick up video information due to th e signal "dropping out". Many VCRs, including Betas, have built-in dropout compensation - the PCM switch on many Sony Betas turns this compensation off, as the compensator basically fills in the missing section with the color of the last good signal so it blends in to the eye, but PCM has its own error-correcting and wandering signals would end up messing with the digital data more
UPC location variant similar to the standard grade horizontal Dynamicrons above

American market L750UHG labels


When professional duplication houses slowed down dubbing of commercial Beta releases, Sony sold off some of their "LS" dubbing blanks of nonstandard lengths free with normal Dynamicron tapes in a Super Saver deal



These tapes came with their white "Copywrited material" tape covers and a small foam blocker inserted into the write-protect tab slot. Neither of my Super Saver cassettes have an original label - they may have not been provided

PAL & SECAM tapes

In PAL and SECAM territories where different recording speeds were not really a thing, the L370 length was also sold as a "regular" length
PAL/SECAM market tapes seem to have been primarily manufactured in Japan, unlike many American market tapes of this generation which were made in the USA

Export diagonal-stripe Dynamicron series (1985 - 1986)

In the mid 1980s the warm-toned color bar motif was changed to run at an angle with a redesigned layout for the export market.

American-market tapes

The grip cutout on the cases was also shallowed, meaning you could no longer see how much tape was on the supply spool without pulling it out

Wrappers for these tapes had a blue "Beta" logo on the back

As time went on, most American buyers gravitated towards using L750 length cassettes, while the L500 and other shorter lengths stayed more relevant in Japan
The ES "Extra Superior" standard grade Dynamicron. They used a smaller magnetic particle size and binder
  Around this time Sony stopped printing different label sheets for different length cassettes, instead giving you small stickers for different lengths. Tellingly, L750 gets two
Later ES-HG L500 with a redesigned back panel more similar to the ES Dynamicron
Updated L750 ES-HG

Japanese Horizontal-format Dynamicrons (1986)

Around 1986 a new range of Japanese Dynamicrons with informative wrappers and simplified cardboard sleeves was released in Japan. These cases were situated horizontally and had a less colorful array of stripes. The tapes are grey with gold text on the tape door.

Nice label sheets for the ES L500 - this one is logged as being recorded first in early 1986
Later High Grade ES-HG L500 for the Japanese market - the wrong tape is in this case

ES-HG L750 with teal stripes. I guess the different colors were for length, not grade, in this generation

Other American-market tapes (1986-1990)

By 1986 the ES had become the standard Sony cassette. In Europe an ES and DX tape were sold with this style of case

By 1986 new high-end machines had Beta Is Super Hi-Band recording, with Super Beta and hi-fi also included on the label

The higher grade American market L750 ESX-HiFi, with a grey cassette and large tape window
  The plastic case for these tapes was actually mostly a textured transparent plastic with only the black and white ESX-HiFi banner at the top printed on it and this card inserted inside

Other Japanese-market tapes (1980s-1990s)

It has thus far been a little bit hard to pin down when exactly some of these different designs of tapes appeared, but I have organized these other Japanese market tapes into what I roughly think is approximately chronological order. If you have any additional information on the specifics of these tapes, get in touch.

Japanese market L500 Master HiFi ESX-HiFi


  Insert for the Japanese L500 ESX-HiFi
  With Beta focusing on the high-end market, tape labels that reference PCM audio and Super Hi-Band recording were common with Japanese Sony tapes

SD L500 variant with a grid on the rear. White plastic slipcases were somewhat of a "thing" for tapes in Japan in the 1990s



Later Japanese market SD "standard" L500



In the late 80s Sony switched to a more open faced cassette design for many of their tapes as well as clear cases as seen on this Japanese market Master HG L500

90s Japanese basic L500 "superfine" that acknowledges the old Beta-square era. Some of these designs I have only come across once... I wonder if any were VCR pack-ins

Later Export Tapes (1990s)

In the 1990s Sony consolidated the NTSC and PAL/SECAM blank tapes into a unified range with labels for multiple regions. I don't really buy sealed tapes online and haven't come across them in the wild as of yet, so I don't have the much more informative wrappers for any of these tapes...

The 1991 standard export Sony tapes had flashy plastic wrappers but a fairly understated design that almost looks better backwards, leading to people storing cassettes "upside down" relative to other cases - not that this actually matters
  Sony only printed one type of international label sheet for these tapes, with different stickers included for NTSC and PAL/SECAM use
  Later on (potentially after PAL/SECAM sales had dropped off) these tapes included only a small single panel label sheet
A very nondescript 90s Beta with a large cassette window and plastic slipcase
  The label sheet is very similar to the later NTSC only variant of the cardboard sleeve 90s Sony but with a grey proof of purchase sticker instead of blue

ED Extended Definition Betas (1988 - 1990s)

In the late 1980s Sony introduced a range of Extended Definition Beta VCRs that packed additional resolution into the recorded image. They use metal particle tape
