BIT PATTERNED MEDIA WITH A SUPER TRACK, READING HEAD AND HARD DISK DRIVE FOR RECORDING/READING DATA ON/FROM THE BIT PATTERNED MEDIA

摘要

A bit patterned medium with a super track, a reproducing head and a hard disk drive for recording/reading data on/from the bit patterned medium are provided to read and separate information stored in a plurality of bit cells at a time by arranging bit cells on each sub-track to cross each other. A bit pattern medium having a super magnetic track comprises: a substrate; and a record film made of a plurality of bit cells which are mutually separately formed according to a plurality of magnetic tracks in which a concentric circle having different radius is composed on substrate. The magnetic track comprises a super magnetic track(130) consisting of a plurality of sub-tracks. Bit cells formed on one sub-track(131,132) among a plurality of sub-tracks are arranged to cross each other with bit cells formed on the other sub-track.
