Unbranded 720K 3.5" Blank DSDD Floppy Disks / Diskettes

These are a mixture of branded and unbranded Brand New 3.5" Blank DSDD Diskettes for use with DD (720K) disk drives.  They are increasingly rare to find - some are branded TDK and Maxell but the majority are unbranded

These also do not have any labels on them and have not been previously used - so are ideal for using your own labels.  We have a small stock of the normal index labels if you require some.

They are 1MB unformatted, but format to provide between 720K and 880K of storage (depending on the system).  They are known as Low Density or Double Density disk drives (compared to the more usual High Density - 1.44Mb disks used on modern disk drives).

These disks are suitable for :

• Commodore Amiga 600, Amiga 1200 and C64 with 1581 3.5" drive
• Atari ST and Mega ST

Also still used by a wide range of industrial machinery from the 1980s onwards - if the system needs 3.5" DSDD disks, these are the ones you need.

In excellent condition and extremely rare to find now.  We also have a few of the even rarer 2.88Mb (or 3.2Mb) ED diskettes!!

Price is per diskette

Bearing in mind the difficulty in finding suitable external DD disk drives and new 3.5" DD disks now, it is worth your while considering whether to replace external disk drives with the new HxC Disk Drive Emulator, which will allow you to store disk images on an SD card - many computers and industrial machinery can use this and move away from floppy disks entirely.
