Inventor: OGASAWARA KENJI
IPC: G11B21/10
Filed: 2000-06-07
Abstract: PROBLEM TO BE SOLVED: To enable eliminating needless spaces between data recording tracks by reading a servo pattern by a positioned read/write head, detecting amplitude of an generated output signal, and detecting that it has become a specific value of amplitude of an output signal from a positioning head.
