Magnetic disk drive where seek speed depends on atmospheric pressure and seek direction

摘要

A magnetic disk drive, which controls the seek and positioning of a magnetic head for recording and reproducing data to a specific position on the magnetic disk in accordance with the servo data recorded in the magnetic disk, comprises measuring means for measuring one of an atmospheric pressure and a height above sea level and head positioning control means for setting a seek speed in accordance with the measured values measuring by said measuring means, and for controlling the seek and positioning of the magnetic head to the specific position on the disk at the set seek speed.
