Filed:

Aug 8, 2003

Appl. No.:

10/637144

Inventors:

Donald Gage - Cedar Park TX, US
Manuel Rivera - Austin TX, US

International Classification:

G11B007/00

US Classification:

369047530, 369053200

Abstract:

Power settings for writing information to an optical medium are adjusted to compensate for variations in the optical medium from expected characteristics, such as recording layer variations, disc tilt, variability in the outer versus inner diameter of an optical medium and write speed variations. An OPC process is performed at each of plural distributed locations of the optical medium, such as an inner diameter, middle diameter and outer diameter location, to determine a power setting at each location that writes information with the least amplitude and jitter variations. The determined power settings for the plural locations are averaged to determine an adjusted power setting for writing information to the optical medium. The adjusted power setting is saved in volatile or non-volatile memory for use in subsequent writes to optical medium having the same identification code.

Appl. No.:

10/901543

Inventors:

Manuel Rivera - Pflugerville TX, US
David Pereira - Austin TX, US

International Classification:

G11B 19/02

US Classification:

369030100, 369047100

Abstract:

An optical drive reads information from an optical medium by measuring the reflectivity of the optical medium to determine the type of optical medium, setting read parameters associated with the determined type and attempting to read identification information from the optical medium to verify the optical medium type. If the identification information verifies the type of optical medium as determined by the measured reflectivity, the optical drive reads information with the read parameters. If the identification information is not readable or fails to verify the measured optical medium type, an alternative optical medium type read parameters are used to read the identification information. If the alternative optical medium type matches the identification information optical medium type, read parameters associated with the alternative optical medium type are used to read information from the optical medium and the user is provided a warning that the optical medium has substandard quality.

Appl. No.:

11/215654

Inventors:

Manuel Rivera - Pflugerville TX, US
Nafisa Muzaffar - Austin TX, US

International Classification:

G11B 19/04

US Classification:

369053210

Abstract:

The present invention provides a method and system that is operable to detect whether optical media has appropriate identification and authentication information. Depending on whether such information is present on the media, appropriate messages are generated for the user and the write strategy for transferring data to the media is adjusted accordingly.

International Classification:

G06F 11/00

US Classification:

714042000

Abstract:

The systems and methods herein may be used for management and capturing of optical drive failure errors. One implementation of a method for capturing a failure error of an optical storage drive may include detecting the failure error of the optical storage drive. The failure error may be characterized by an error identifier, which may be stored in a drive memory. In certain embodiments, methods herein may also include storing media information available on optical storage media to the extent that such media information may be available. Among other advantages, storage of error identifiers and/or media information may aid manufacturers in diagnosing problems with returned optical storage drives.
