Over-The-Rail Write Driver For Magnetic Storage Systems
US Patent:
2014002, Jan 30, 2014
Filed:
Jul 27, 2012
Appl. No.:
13/560815
Inventors:
Paul Mark Mazur - Cottage Grove MN, US
Michael Joseph Peterson - Eagan MN, US
Michael Joseph Peterson - Eagan MN, US
Assignee:
LSI CORPORATION - Milpitas CA
International Classification:
G11B 5/09
US Classification:
360 46, G9B 5033
Abstract:
A write driver circuit for generating a write current pulse for use by a magnetic write head includes an output stage adapted for connection with the magnetic write head and a charge storage circuit connected with the output stage. The charge storage circuit is operative in a first mode to store a prescribed charge and is operative in a second mode to transfer at least a portion of the charge stored therein to the output stage to thereby enable an output voltage level of the output stage to extend beyond a voltage supply rail of the write driver circuit. A control circuit in the write driver circuit is operative to generate at least one control signal for selectively controlling a mode of operation of the charge storage circuit.
Storage Device Having Write Signal With Multiple-Slope Data Transition

Assignee:
LSI Corporation - Milpitas CA
International Classification:
G11B 5/09
US Classification:
360 40, G9B 5033
Abstract:
A hard disk drive or other disk-based storage device comprises a storage disk, a read/write head configured to read data from and write data to the disk, and control circuitry coupled to or otherwise associated with the read/write head. The control circuitry comprises a write driver configured to generate a write signal for data to be written to the storage disk, and a multiple-slope transition controller associated with the write driver and configured to control a data transition in the write signal such that the data transition comprises at least two different segments each having a different slope, with the transition controller comprising separate slope control mechanisms for each of the segments. By way of example, the data transition may comprise a dual-slope transition having first and second segments arranged sequentially between a start point and an end point of the data transition.

International Classification:
G05F 1/00
US Classification:
323282
Abstract:
A voltage regulator, a method of regulating voltage and an IC including a voltage regulator. In one embodiment, the voltage regulator includes: (1) a DC precision amplifier configured to generate a DC precision signal based on a reference voltage and a regulated output of the voltage regulator and (2) a response amplifier, coupled in parallel with the DC precision amplifier, configured to generate an error signal based on the reference voltage and the regulated output, the response amplifier further configured to generate the regulated output based on a regulating signal comprised of the error signal and the DC precision signal. The DC precision amplifier may be a CMOS amplifier and the response amplifier may be a NPN amplifier.

International Classification:
G11B 5/465
US Classification:
360111
Abstract:
A hard disk drive or other disk-based storage device comprises a storage disk, a write head configured to write data to the disk, and control circuitry coupled to the write head. The control circuitry comprises a write driver and degauss circuitry associated with the write driver. The degauss circuitry is configured to generate a degauss signal to be applied to the write head by the write driver. The degauss signal has a waveform comprising a plurality of decay segments including at least one alternating current decay segment and at least one direct current decay segment. An initial decay segment of the plurality of decay segments may comprise an alternating current decay segment or a direct current decay segment, and may be immediately followed by a decay segment of the opposite type.

Abstract:
A hard disk drive or other disk-based storage device comprises a storage disk, a write head configured to write data to the disk, and control circuitry coupled to the write head. The control circuitry comprises a write driver and degauss circuitry associated with the write driver. The degauss circuitry is configured to generate a chirped degauss signal to be applied to the write head by the write driver. The degauss circuitry comprises a ramp generator configured to generate a ramp signal for controlling a frequency of at least a portion of a waveform of the chirped degauss signal. The ramp signal generated by the ramp generator may comprise a current ramp that is applied to a control input of a current controlled oscillator of the degauss circuitry.
