MAGNETIC DISC AND MAGNETIC APPARATUS |
摘要 |
A magnetic disc and a magnetic disc apparatus increases the number of the sectors on the external peripheral side of the magnetic disc more than that of the internal peripheral side so as to increase the recording capacity, wherein the tracks are divided into a K group of zones from the internal periphery of the magnetic disc to the external periphery thereof, and the number of the sectors of the track group on the external peripheral side is composed to be more than the inner peripheral side, so that a simple data face servo-system high in interchangeable property may be used with the number of the servo sectors being made constant. <IMAGE> |
