The technology involved reading and writing data magnetically, while optically aligning the read/write head in the drive using grooves in the disc being sensed by an infra-red LED. The magnetic head touches the recording surface, as it does in a normal floppy drive. 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. Floptical disks provided 21 MB of storage. The drive had a second set of read/write heads so that it could read from and write to standard 720 kB and 1.44 MB (1,440 KiB) disks as well. | The technology involved reading and writing data magnetically, while optically aligning the read/write head in the drive using grooves in the disc being sensed by an infra-red LED.
