Floptical was a brand of drive introduced in 1991 by Insite Peripherals, and was also the name of the technology which was a type of floppy disk combining magnetic and optical systems. Floptical disks were the same size as the standard 3.5-inch floppy disk, and Floptical drives could read these using a second set of read/write heads.
Data is written to the disk magnetically, while optically aligning the read/write head in the drive using grooves in the disc being sensed by an infra-red LED. The optical servo tracks allowed for an increase in the tracking precision of the magnetic head, from the usual 135 tracks per inch to 1,250 tracks per inch, allowing 21 MB of storage.
Insite licensed the floptical technology to a number of companies and a number of these formed the Floptical Technology Association, or FTA, to try to have the format adopted as a floppy replacement.
Around 70,000 Floptical drive are believed to have been sold worldwide in the product’s lifetime, although it had lingering quality and reliability issues, and was generally much slower than other technologies such as the Iomega Zip. Iomega had licensed the Floptical technology, but dropped it in favour of their own Zip drive.
