An optical medium associated with a first type of optical drive laser, such as a blue laser, embeds identification information readable by a second type of optical drive laser, such as a red laser associated with DVD media or an IR laser associated with CD media, in order to reduce the time used by the optical drive to recognize media. An attempt to read the embedded identification information by the second laser that succeeds provides the optical drive with the information to proceed with use of the optical medium using the first laser. An attempt to read the embedded identification information that fails provides the optical drive with the opportunity to detect whether the optical medium is associated with the second laser so that a single spindle kick of the optical medium by the optical drive determines whether the optical medium is associated with either of two types of lasers.

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.

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.

A method, system and apparatus for testing a removable storage media drive device are disclosed. According to teachings of the present disclosure, a simulated storage media may be disposed within a removable storage media drive device. In the event removable storage media is not present in the drive device when testing of the device is desired, the simulated storage media may be substituted for at least purposes of testing the operability of one or more device components. In one embodiment, the simulated storage media may be in the form of an annular ring of CD-ROM material. In a further embodiment, the simulated storage media may be in the form of a hologram designed to mimic one or more removable storage media characteristics.

Expiration information stored on an optical medium is applied to determine an expiration date of the optical medium that provides a predetermined reliability of information archived on the optical medium, such as a predetermined acceptable defect level of the information at the expiration date. An expiration engine associated with an information handling system or optical disc drive determines the expiration date from one or more factors, such as the manufacture date of read-only optical media, the initialization date of recordable optical media, a quality rating associated with a defect growth rate over time of the optical media, and a desired reliability. In one embodiment, the expiration engine writes expiration information to the optical media, such as a date stamp at initialization of a recordable optical medium. Alternatively, an expiration date is stored on an information handling system to provide expiration warnings a predetermined time before the expiration date.

System and method for optical media information storage life tracking

An optical medium storage device improves the usable life of re-writable optical storage mediums, such CD-RW, DVD+RW and DVD-RAM disks, by adjusting write parameters to compensate for time between an initial write on the optical storage medium and the current time, with adjusted write parameters fine-tuning signal-to-noise ratios and improving the number of reliable overwrites for the optical storage medium. A time compensator determines the time delta between an initial write on the optical storage medium, such as formatting of the medium, and the current time, and then applies the time delta to determine a time compensation factor that adjust the write parameters of a focused laser beam that writes information to the optical storage medium

Separate sets of optical medium identification information are embedded in separate aligned layers of the optical medium to allow an optical drive to initiate use of the optical medium with information from both layers. For instance, a first set of identification information is embedded in the data layer of the optical medium and a second set of identification information is embedded on the protective surface layer of the optical medium. The first and second sets of information align so that a mixed signal is provided when the optical medium is initially inserted in the optical drive with the optical drive reading the separate sets of information while the read head is at a single location.

Optical medium aligned information system and method

An optical storage reconditioning module extends the life of re-writable optical medium, such as DVD+RW optical storage disks, by writing random information to recondition commonly used portions of the optical medium before re-writing information to those portions of the optical medium. For instance, a stored file system structure of an optical medium, such as a Universal Disk Format (UDF) random writable file system, is updated by reading to a buffer the structure from the optical medium, over writing the structure with random information recondition transitions between data points of the structure, updating the file system structure in the buffer and writing the updated file system structure over the random information.

Method and system for reconditioning optical storage media to write updated information

Optical medium identification codes, such as the ATIP start codes used for CD-R optical media, are preassigned by optical medium manufacturer for association with planned optical media of the manufacturer. Optical disc drive manufacturers build optical disc drives having the preassigned optical medium identification codes in write strategy tables even though the optical disc drives are manufactured and sold before release and development of write strategies for the planned optical media. General write strategies associated with the preassigned optical medium identification codes provide more rapid write speeds for optical media having preassigned codes than for optical media having unknown identification codes by basing the preassigned write strategies on planned optical media design parameters, such as similarities with existing optical media of the manufacturer.
