IPC: G11B5/55
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption and extend the life of a battery, by determining a variable indicating the time required for shifting an actuator from a current track and a current sector to a target track and a target sector and a variable indicating the time until a target servo sector proceeds from a current servo sector to a radial arc, and then comparing both variables.
