Abstract
A universal portable minidisk drive system adopts the (1) universal head (2) laser pin (3) timing/coordinate clock track to have the long-time, continue-playing for all the different disk media such as optic disk, magnetic disk or magnetopic disk. The universal head enables the universal disk to read/write all the different disk that the portable computer only needs to have one kind of disk drive. The laser pin pushes the track density to the extreme limit that the minidisk can store a large amount data. The timing/coordinate clock track introduces the (track, sector) coordinate system to the disk that the access/recover time is reduced. The disk drive can play continuously in the vibrant environment.
