Disk Drive To Reduce Head Instability

US Patent:
7974039, Jul 5, 2011
Filed:
Jun 17, 2009
Appl. No.:
12/486682
Inventors:
Jianfeng Xu - San Jose CA, US
Kazuhiro Saito - San Jose CA, US
Hongchao Tim Zhao - San Jose CA, US
Assignee:
Western Digital Technology, Inc. - Irvine CA
International Classification:
G11B 21/02
G11B 27/36
US Classification:
360 75, 360 31
Abstract:
A disk drive to reduce head instability during disk drive manufacturing is disclosed. The disk drive comprises: a disk; a dynamic flying height (DFH) read/write head; a flying height actuator to control the spacing between the DFH read/write head and the disk; and a controller. The controller controls operations in the disk drive including applying a sloped increasing power between a first voltage and a second voltage to move the DFH read/write head towards the disk.
