Title: Magnetic head feeding mechanism
Inventor: ISHIDA HITOSHI
IPC: G11B33/08
Filed: 1989-06-02
Abstract: PURPOSE:To stabilize contact between a magnetic head and a magnetic disk after seek is finished and to shorten seek settling time by locking a vibration attenuating member in a carriage seek direction to a step motor lead screw groove. CONSTITUTION:In a magnetic head feeding mechanism, the vibration attenuating member in the carriage seek direction is locked to a step motor lead screw groove 3b. Accordingly, when each track in the radial direction of the magnetic disk is seeked by a carriage 2 loading a magnetic head 1, even in the case that dumping is generated by a motor characteristic in the end of the seek while the carriage 2 is fixed, this dumping is regulated to a rigid by the carriage seek direction vibration attenuating member locked to a step motor lead screw 3a. Thus, the vibration of the magnetic head loading carriage in the seek direction is early attenuated and the contact is stabilized between the magnetic head 1 and magnetic disk after the end of the seek. Then, the seek settling time widely is shortened.
