The 3" discs for the Amstrad Disk Drive are called CF2 (Compact Floppy Disc). CF2 discs were produced by AMSOFT, MAXELL, Schneider, Panasonic. In late eighties, cheaper Noname discs were also available (although these were rather unreliable).
Capacity is 180 Kbytes per side (the discs can be flipped to access the other side, giving a total of 360 Kbytes per disc).
(This article, File:Amstrad Computer User8504 072.jpg, also mentions something called Hitachi HFD-2 discs.)
3 Inch Discs Comments from John King
There is not much to be said about these 3 inch discs other than there is only one type but produced by a number of different manufacturers -- some good quality, many bad quality. I have identified what the years have shown me to be good quality, long lasting discs but beware do not judge the discs you might be offered by their paper labels as many cheap copies from suspect makers have appear in the market place, look at the discs themselves. The Good
Genuine Amsoft (Amstrad) 3" CF-2DD: This type of disc was originally supplied for the double head 720K drives at an enhanced price, then Amstrad admitted that these discs were no different to their other offering (see the first disc).
The Bad
- Dixions Store supplied: Found to be unreliable and not to servive the rigours of time -- to be avoided at all costs!
- Maker Unknown - Blank6 & Blank11: These discs are found to be unreliable and do not last the rigours of time -- to be avoided at all costs.
- Copy (or poor quality) Amsoft: These discs normally come with an Amsoft label and I am lead to believe that they are cheap copies -- to be aviod at all costs. These discs tend to become corrupt and or fall to pieces.
- Wiz Disc: Origin of manufacture is unknown but a test of six discs from the same batch revealled that most would not format to 720K but were fine at 180K -- to be avioded at all costs.
- Diskxpress: Supplied by Diskxpress -- to be avioded at all costs.
