Spin Stand Comprising A Dual Disk Clamp
US Patent:
8331056, Dec 11, 2012
Filed:
Mar 5, 2010
Appl. No.:
12/718910
Inventors:
Thomas A O'Dell - Sunnyvale CA, US
Assignee:
WD Media, Inc. - San Jose CA
International Classification:
G11B 17/038
US Classification:
360 9808
Abstract:
A spin stand is disclosed comprising a spindle motor having a rotor. A first disk clamp is operable to clamp a first disk to the rotor, and a second disk clamp is operable to clamp a second disk to the rotor. An actuator is operable to clamp the second disk clamp in order to clamp the second disk to the rotor after the first disk has been clamped to the rotor.

International Classification:
G11B 21/02, G11B 17/038
US Classification:
360 75
Abstract:
A method of processing disks on spin stand is disclosed, the spin stand comprising a spindle motor having a rotor. A first disk is clamped to the rotor, wherein the first disk comprises a reference servo pattern. A second disk is clamped to the rotor, and a first head is servoed over the first disk in response to the reference servo pattern in order to position a second head over the second disk at a first radial location. Data is written to the second disk at the first radial location using the second head. The second disk is removed from the rotor while the first disk remains clamped to the rotor.
Discriminating Between Protrusion Defects And Recess Defects On A Disk Recording Medium
US Patent:
8427770, Apr 23, 2013
Filed:
Sep 2, 2011

Assignee:
WD Media, LLC - San Jose CA
International Classification:
G11B 27/36
US Classification:
360 25, 360 31
Abstract:
An apparatus is disclosed comprising a thermal sensor operable to detect at least one protrusion defect and at least one recess defect on a disk, the thermal sensor operable to generate a sensor signal. An attack time of the sensor signal is measured when the thermal sensor passes over one of the protrusion defect and the recess defect, and the protrusion defect is discriminated from the recess defect based on the attack time.
