Non-Volatile Write Cache, In A Disc Drive, Using An Alternate Power Source

View page
US Patent:
20020029354, Mar 7, 2002
Filed:
Jun 27, 2001
Appl. No.:
09/894152
Inventors:
Monty Forehand - Yukon OK, US
Kevin Fruendt - Yukon OK, US
Virat Thantrakul - Oklahoma City OK, US
Assignee:
Seagate Technology LLC
International Classification:
G06F001/26
G06F001/28
G06F001/30
G06F011/30
US Classification:
713/340000
Abstract:
A non-volatile write cache using an alternate power source is implemented in a disc drive to maintain the integrity of cached write commands during a standard disc drive power loss, and to further recover and execute outstanding cached write commands when standard disc drive power is restored. The disc drive includes an internal or external alternate power source, control circuitry to switch between normal and low-power modes, memory control circuitry to, when in low-power mode, maintain the refresh of the cache, and firmware to recover and execute cached write commands once power is restored.

Long-Term Asymmetry Tracking In Magnetic Recording Devices

US Patent:
20090201602, Aug 13, 2009
Filed:
Feb 8, 2008
Appl. No.:
12/028131
Inventors:
Aravind Raghunathan - E. Shakopee MN, US
Kevin Dean Fruendt - Oklahoma City OK, US
International Classification:
G11B 5/596
US Classification:
360 7702
Abstract:
A technique tracks head asymmetry of a magnetic recording device over time. In particular, a reference pattern having a known fundamental/reference frequency may be read from a reserved track of a magnetic recording medium to produce a response signal, and signal power may then be determined at the reference frequency and at a second harmonic component frequency of the reference frequency. Accordingly, head asymmetry for the device may be tracked based on a ratio of the signal power at the second harmonic component frequency to the signal power at the reference frequency.
