Phase Lock Loop For Optical Disc Drive And Optical Media With Wobbled Grooves

View page
US Patent:
20040095863, May 20, 2004
Filed:
Nov 7, 2003
Appl. No.:
10/704294
Inventors:
Johannes Verboom - Colorado Springs CO, US
Fred Wamble - Colorado Springs CO, US
Kurt Getreuer - Colorado Springs CO, US
Keith Holstine - Colorado Springs CO, US
International Classification:
G11B007/00
US Classification:
369/047280, 369/047480
Abstract:
A system and method for use in a data storage system which provides a combined phase lock loop (PLL) that utilizes a common Voltage Controlled Oscillator (VCO) and common integrator/loop-filter, but which is operational in a wobble-mode and a data-mode to provide most optimum operation and quick capture. Digital circuitry is primarily used in addition to the VCO and a loop-filter for acquiring frequency and phase lock while the optical disc drive is writing and reading. A digital Phase-detector for operation in the wobble-mode employs a down-counter that can be configured for both Frequency-Lock and Phase-Lock in a way that offers a large capture range and can adapt quickly to the multiple data-zones of the media-format.

Optical Data Recorder With Segment Synchronization Marks

View page
US Patent:
52951278, Mar 15, 1994
Filed:
Dec 22, 1992
Appl. No.:
7/994574
Inventors:
Johannes J. Verboom - Black Forest CO
Fred N. Wamble - Colorado Springs CO
Assignee:
North American Philips Corporation - New York NY
International Classification:
G11B 390
G11B 2736
G11B 700
G11B 370
US Classification:
369 58
Abstract:
The beginning of a segment within a track of a record carrier, having a plurality of frames in each segment, is identified by detecting the presence of a control mark at a given position near the beginning of a frame, and the absence of a control mark at an adjoining position at which a control mark will be found in all other frames of the segment. The other frames of each segment are free from a mark at the given position. The next bit position containing a mark, after the given position and its adjoining position, is the clock bit position used for bit clock synchronization. An apparatus for reading these marks may include a qualification circuit for evaluating the magnitude of the difference in detector output at the given bit position and the adjoining bit position.

Method And Apparatus For Maximum Likelihood Detection

View page
US Patent:
60916877, Jul 18, 2000
Filed:
Dec 19, 1997
Appl. No.:
8/994874
Inventors:
Johannes J. Verboom - Colorado Springs CO
Fred N. Wamble - Colorado Springs CO
Assignee:
Philips Electronics N.A. Corporation - New York NY
International Classification:
G11B 700
US Classification:
369 59
Abstract:
A method and apparatus for recovering data from an optical read channel provides for improved recording density by tolerating lower phase and amplitude margins. The method includes digitizing a plurality of samples of a first signal, clipping the digitized samples of the first signal, digitally differentiating the clipped digitized samples, determining the relative locations of signal polarity changes, and generating logical values for channel bits based, at least in part, on the relative locations of signal polarity changes. The apparatus for recovering data from an optical read channel includes a signal-level limiter, a digital differentiator coupled to the signal-level limiter, a min/max detector coupled to the digital differentiator, a zero-crossing detector coupled to the digital differentiator, an update signal generator coupled to the zero-crossing detector and the min/max detector, and a channel bit transition generator.
