In a magnetic tape drive having a plurality of stepped operational speeds, data storage logic estimates, from the effective data fill rate for a data buffer and the drive data write rate, the time cost to continue to operate the magnetic tape drive at the current stepped operational speed from a target to the next end of wrap; estimates, the time cost to force a backhitch of the magnetic tape data storage media and change the stepped operational speed to a higher stepped operational speed and operate the magnetic tape drive at the higher stepped operational speed to the next end of wrap; and determines the lesser time cost.

A tape cartridge having dual cartridge memory modules to provide memory redundancy, and a method and apparatus for providing redundancy of cartridge memory information within a tape cartridge. The tape cartridge comprises at least first and second cartridge memory modules, each of which stores an identical set of critical information. Each of the first and second cartridge memory modules includes enough critical information to recover from a failure of either of the cartridge memory modules. The method comprises the steps of providing at least two cartridge memory modules in the tape cartridge, and storing an identical set of critical information in each of the two cartridge memory modules. Each of the two cartridge memory modules includes enough critical information to recover from a failure of either cartridge memory module. In a preferred embodiment, the CM modules are stacked one on top of another and increase the amount of space available for tape directory storage.

Diagnostic information is provided in an automated data storage library which stores magnetic tape data storage cartridges. Uninitialized magnetic tape data storage cartridges are identified; a diagnostic scan is conducted by a drive of the library of the servo tracks on magnetic tape of an identified cartridge using write criteria for a diagnostic test; the results of the diagnostic test are logged by the drive; and the logged results of the diagnostic test are collected at the library controller.

A diagnostic for magnetic tape data storage drives and magnetic tape data storage cartridges comprises a magnetic tape data storage drive having more stringent servo error detection in write mode than in read mode. The magnetic tape data storage drive is set to a write mode, the write mode nominally for operating the write channel to write data while the track following servo apparatus detects and track follows the servo tracks of a magnetic tape; and scans the servo tracks of a magnetic tape in the write mode, but without writing data; detecting servo errors using criteria of the write mode; and logs information of the detected servo errors.

An apparatus, system, and method for automatic unthreading and storage of storage media helps prevent damage to the media, which can otherwise occur when the storage media is left threaded in a storage media drive over an extended period or under adverse conditions. A sensing device may generate a signal or a detector may receive a signal indicating that a predetermined period of time has lapsed or that some other criteria has been met indicating that the storage media should be removed from the storage media drive. An unthread module in the storage media drive receives the signal and automatically unthreads and stores the storage media. A location on the storage media can be marked by the unthread module prior to unthreading such that the media may be returned to the location upon rethreading.

In a data storage device, information regarding the operation of the device is gathered by a plurality of information providers or sources, such as counters, each configured to indicate a data point and/or count the occurrence of events with respect to the data storage device. A device control is configured to present an external prestructured arrangement of potential monitoring of the information providers, for external selective monitoring of a portion of the information providers in accordance with the prestructured arrangement. In one example, the prestructured arrangement is an ordered sequence of the information providers, for selective monitoring of a selected number of the information providers taken from the ordered sequence, such as the first “n” of the sequence.

A write-once read-many (WORM) optical disk recorder automatically calibrates its laser to emit a laser beam of a desired power level. While writing data to the WORM disk, a laser test signal is written to a laser checking area termed Automatic Laser Power Correction (ALPC) field. If the emitted laser test signal has a power level outside an acceptable power level window, then inappropriate laser power is indicated. Then, in an error recovery procedure (ERP) the laser power is calibrated in the data sector to be written to using short spaced-apart laser test signals. After successful calibration, data are written to the sector. The test signals appear as burst errors that can be corrected by a suitable error correction code. If such calibration is not successful then a write calibrate sector, WCS, is created and used for an extensive automatic calibration. In the WCS both laser power level is calibrated.
