Quick Disks for the S-10, S-220, MKS-100, MT-100 and PR-100.
The Quick Disk (QD) was a media storage disk system made by Mitsumi Corporation as an alternative to the 5 1/4 inch floppy disk which was the standard at that time. The Quick Disk was used on some older Roland products such as the S-10, S-220, MKS-100, MT-100 and PR-100. Quick Disks were also used on some brands of "smart" typewriters such as the Smith-Corona and a variation of the Quick Disk was also used by Nintendo in their game products of that era. None of these other companies have any remaining parts or replacement drives. Smith-Corona was the last known source for Quick Disk drives and parts. At this time, Smith-Corona is no longer in business and their last remaining left-over parts were sold off many years ago.
The are currently no known sources remaining for Quick Disks or Quick Disk drives and parts.
