2" Disks

Postby Arne » Fri Oct 26, 2018 7:29 pm

Some 20+ years ago I bought som 2" (2 inch) disks on a local computer fleemarket (pre ebay era). Does anybody know where they were used? Google wasn't helpful here at all.

I remember seeing them in music shop back in the late 1980's or early 90's can't quite remember the exact time but it was around there. They were with a synth / sampler package they were selling, I think it was Roland. I just remember flicking through the disks as when I first looked at them I thought the were for the ST.

Oh... it does remind me of the VF-50 video floppy disk... I think it's the same...

Some info here: http://www.garpenholm.se/vf-50/

Basically it was a special, semi analog disk format specificaly for stillbild cameras, like a predecessor for todays digital cameras.

something like that... I think...

They were used with one of the first digital cameras in the 80s I believe it was the Canon RC-250. I have one of these cameras and a box of floppies still somewhere.

Thanks guys!
I thought that it was for Japanese niché market as they did not use IBM, Macs, STs, Amigas back in the 80s/90s and had their own machines like Sharp X68000, FM Towns...
Always hoped to get a disk drive for these disks but in the end it probably wouldn't have a shugart bus either.

@fmh: how did you transfer the pictures on the disk to PC.... whatever? Did Canon offer an external FDD?

A friend had a Canon digital camera using video floppy, I borrowed it and as I remember you had to hook the camera up to the serial port of your computer to transfer the images.

if you read wikipedia, apparantly there was 2 different 2" floppies around, one that indeed was digital formatted.

Another one, the LT-1, is digitally formatted—720 kB, 245 TPI, 80 tracks/side, double-sided, double-density. They are used exclusively in the Zenith Minisport laptop computer circa 1989

I think I saw them once at a Doctor's office used with an electric typewriter or word processing system. But that was around 1992 or so.

Could that have been an Amstrad/Schneider PCW with 3"-disks?

No, it was probably a Japanese brand, Epson, Sanyo or something. I would have recognized any Amstrad/Schneider branded device back then.
