Title: Reference track detecting method for disk storage
Inventor: MIYASHITA TAKASHI
IPC: G11B21/08
Filed: 1987-12-29
Abstract: PURPOSE:To exactly detect a reference track without using an exclusive-use position detector by writing servo information with relating a border between a writing range and a non-writing range with the reference track in advance, detecting the border from the change of the presence and absence of servo information contents and calculating the radius direction position of the reference track. CONSTITUTION:To a remained part excepting at least one part of the non- writing range out of the setting range of the track in the radius direction range of a disk 1 which can move and operate a head 3, servo information SI are written with relating the border between the writing range and non-writing range with a reference track RT in advance. By causing a vector designating means 10 to successively designate a vector to a head operating motor 5, the servo information SI are read by a servo information reading means 20 while the head 3 is successively moved in the prescribed radius direction. Then, by calculating the radius direction position of the reference track RT from the detected border, the reference track is detected as a reference point to move and operate the head 3. Thus, the reference track RT can be detected easily and exactly and cost and space for a position detector can be wholly omitted.
