Abstract:
1. A magnetic disk apparatus comprising: a magnetic disk having a magnetic film formed on a substrate; a spindle motor for rotating said magnetic disk; a magnetic head provided for movement in facing a surface of said magnetic disk; a driving mechanism for positioning said magnetic head to a track determined on said magnetic disk; a magnetic writing/reading circuit by which said magnetic head conducts writing/reading of information along said track; an interface means for sending/receiving said information and signals for controlling said information to/from an external information processing device; a locking mechanism operable during on-times of the magnetic disk apparatus, the locking mechanism locking a movable part of said magnetic disk apparatus during non-use on-times of the magnetic disk apparatus, said locking mechanism releasing the locking of the moveable part during on-times when a specific command is issued from the external information processing device, and re-locking the moveable part during on-times again after processing of the specific command is completed, to keep a locking of the moveable part during any of the non-use on-times until a subsequent specific command is issued from the external information processing device; and wherein said magnetic disk is stopped after the specific command is completed, and the moveable part of said magnetic disk or said spindle motor is latched on the basis of detection result of detection means for detecting that the magnetic disk is not being rotated.
