Abstract
A head carriage lock mechanism for a magnetic disk drive has a lock member, a lifter, a link member and a solenoid. The lock member is shaped in the form of a quadrilateral frame, with arms extending perpendicularly from a front panel and a rear panel so as to connect the two panels. The right arm of the lock member, which approaches the head carriage, has a rack that engages an engaging portion of the head carriage so as to lock the head carriage in place so as to prevent damage to the head carriage during transport. The solenoid that drives the lock mechanism is positioned inside the space enclosed by the frame of the lock member, making more efficient use of the space inside the disk drive and making it possible to make the disk drive more compact.
