20080198722 | Optical Recording Using Secondary Tracking Method - The present invention is embodied in a method for storing computer readable data on a removable storage medium, including using a first wavelength to write data to the removable storage medium, using a second wavelength to maintain radial tracking on the removable storage medium, wherein the second wavelength is shorter than the first wavelength, and maintaining axial tracking on the removable storage medium with at least one of the first wavelength or the second wavelength. | 08-21-2008 |
20080212420 | System and Method for Embedding Optical Drive Compatibility Information in Optical Media - Compatibility information embedded in an optical medium modifies actions allowed by predetermined non-compatible optical disc drives on the optical medium, such as optical disc drives that may suffer damage if certain actions are performed on the optical medium. For instance, a compatibility engine of the optical disc drive applies compatibility information read from an optical medium to determine restrictions to impose on the use of the optical medium, such as restricting the optical disc drive from writing to the optical medium, reading from the optical medium or performing any operations until an update to the optical disc drive firmware is performed either automatically or by display of a compatibility user interface at an information handling system associated with the optical disc drive. In one embodiment, the compatibility information identifies incompatible optical disc drives and firmware versions by unique identifiers. | 09-04-2008 |
20090006749 | DRIVE TRACKING SYSTEM FOR REMOVABLE MEDIA - A system, and associated methods, comprises a storage drive adapted to accommodate a removable storage medium and a central processing unit (“CPU”) configured to execute code. The code causes the storage drive to record audit information onto the storage medium. The audit information may comprise an identifying value identifying the storage drive and a time value indicative of when data was recorded to the storage medium. | 01-01-2009 |
20090282190 | DATA STRUCTURE FOR CONTROL INFORMATION ON REWRITEABLE DATA STORAGE MEDIA - A data storage medium includes a data structure, called a disk control block, used for administration and control information for the data storage medium. One medium may contain multiple different disk control blocks, each addressing a different function. Each disk control block includes a control block identifier that specifies the function of the disk control block. Each control block also includes a set of standard access control parameters. If a drive encounters an unrecognized disk control block, the drive can still decode the standard control parameters, so that the drive behavior is not inconsistent with the requirements of the unrecognized disk control block. | 11-12-2009 |
20090310449 | System And Method For Embedding Optical Drive Compatibility Information In Optical Media - Compatibility information embedded in an optical medium modifies actions allowed by predetermined non-compatible optical disc drives on the optical medium, such as optical disc drives that may suffer damage if certain actions are performed on the optical medium. For instance, a compatibility engine of the optical disc drive applies compatibility information read from an optical medium to determine restrictions to impose on the use of the optical medium, such as restricting the optical disc drive from writing to the optical medium, reading from the optical medium or performing any operations until an update to the optical disc drive firmware is performed either automatically or by display of a compatibility user interface at an information handling system associated with the optical disc drive. In one embodiment, the compatibility information identifies incompatible optical disc drives and firmware versions by unique identifiers. | 12-17-2009 |
20110082974 | SYSTEM AND METHOD FOR WRITING DATA AND A TIME VALUE TO AN ADDRESSABLE UNIT OF A REMOVABLE STORAGE MEDIUM - A system (and associated method) comprises a storage drive and a central processing unit (“CPU”). The storage drive is adapted to accommodate a removable storage medium. The CPU is configured to cause the CPU to write data and a time value to each of a plurality of addressable units of the storage medium in which data is written. The time value is indicative of the time at which each addressable unit was written with data. | 04-07-2011 |
20110103213 | System and Method for Embedding Optical Drive Compatibility Information In Optical Media - Compatibility information embedded in an optical medium modifies actions allowed by predetermined non-compatible optical disc drives on the optical medium, such as optical disc drives that may suffer damage if certain actions are performed on the optical medium.

20140143515 | VIRTUAL WRITE PROTECTION SYSTEM - An optical medium containing virtual write protect information can be recorded in drives and systems without first changing the write protection from on to off by receiving valid user input. The virtual write protection may also be enabled or disabled by additional information on the disc. | 05-22-2014 |
20140212115 | OPTICAL DISC WITH THREE-DIMENSIONAL VIEWING DEPTH - An optical disc is encoded with first, second, and third sets of video data. The first set of video data is for generating a first video stream for a first eye of a viewer. The second and third sets of video data are for second and third video streams for a second eye of a viewer. The first and second sets of video data provide a first level of three-dimensional (3D) viewing depth, and the first and third sets of video data provide a second level of 3D viewing depth. | 07-31-2014 |
