A 16MB 3.5 inch Ba-Ferrite flexible disk drive with dual track following servo modes

A large capacity high-speed-access 3.5 inch flexible disk drive has been achieved, using a barium ferrite 3.5 inch flexible disk and newly developed sector servo technology. The flexible disk drive has a 16 megabyte unformatted capacity, a 50 millisecond average seek time and a 3 megabit/second data transfer rate. It can use both concentric track disks for conventional computer systems and spiral track disks for high speed data transfer systems, such as hard disk drive (HDD) back-up, image data storing, and so on.
