Is there some kind of disk image somewhere ? I know that the Famicom Disk System used this kind of disk, but the track format is different no ? To be able to do something i really need more informations. Almost a fast version of a cassette tape. So overall there is no concept of an index or directory.not even sure their is a traditional dis controller. Unusually, the Quick Disk utilizes "a continuous linear tracking of the head and thus creates a single spiral track along the disk similar to a record groove." This has led some to compare it more to a "tape-stream" unit than typically what is thought of as a random-access disk drive.

The Quick Disk interface cartridge will provide a ROM with special QuickDisk BASIC commands This makes QD much slower then competing disk storage systems.ĭeleting files is also a problem, and you can only delete the last file or format the disk and start from scratch. Data is recorded in a spiral and the whole disk needs to be scanned to do a directory listing. Instead of using tracks like regular disks, and a file system with directory, it is more similar to tape.

The Quick Disk uses a Z8440 Serial Input/Output Controller at a certain clock speed, it lacks the WR signal because it is synchronised with the clock of the Z80. This storage device can be used with any MSX generation, but when used with Turbo R machines, it's limited to the Z80 mode (which implies booting while pressing the "1" key until you can hear a beep). Both the drives and the media are quite rare now.
This format never really caught on in the MSX world.
A Quick Disk (QD) is a magnetic disk of 2.8" designed by Hitachi Maxell, Ltd, and the drive was designed by Mitsumi Electric Co., Ltd in 1984.
