Disclosed is a disk drive having a disk, a masked read-only memory (ROM) device, a reprogrammable nonvolatile memory device, and a microprocessor for executing program code. The disk has a magnetic data storage surface with embedded servo wedges for defining data storage tracks including reserve tracks. The masked ROM device stores program code for implementing a spindle motor controller, program code for implementing a portion of a servo controller for track following along a data storage track, and program code for implementing a portion of a disk controller for controlling writing disk data to and reading disk data from the reserve tracks. The reprogrammable nonvolatile memory device stores data parameters relating to the disk drive's configuration. The reserve tracks store program code for implementing a cache control system for controlling caching of disk data in a cache memory.

A control system and method for operating a system comprising a host computer, a buffer, a tape drive and a tape is provided. The method includes writing data to the tape while the tape is traveling at a first speed; stopping the tape; determining an optimum second speed to drive the tape to travel; and, thereafter driving the tape to travel at the second speed while writing data to the tape.

A method for providing enhanced readability of data written to a magnetic tape, includes the steps of (i) writing data to a first tape partition using a tape drive, the data being written under a first dimensional stability condition; (ii) monitoring an ambient dimensional stability condition with a condition monitor to determine if the ambient dimensional stability condition has moved at least a predetermined threshold value from the first dimensional stability condition toward a preferred dimensional stability condition; and (iii) replicating the data to a second tape partition with a data replicator when it has been determined that the ambient dimensional stability condition has moved at least the predetermined threshold value from the first dimensional stability condition toward the preferred dimensional stability condition.

A tape cartridge for use in one or more tape drives of a tape library includes a cartridge housing and a magnetic tape. The magnetic tape is retained within the cartridge housing. The magnetic tape includes a first tape section that is pre-recorded with calibrated data for evaluating data durability on the magnetic tape. The magnetic tape is usable within the tape library to measure a health of the one or more tape drives and/or confirm a suitability of an operating environment within the tape library in terms of at least one of temperature and humidity. The calibrated data in the first tape section can be further configured for evaluating total transverse dimensional stability on the magnetic tape. The first tape section can include predetermined error patterns to assist in evaluating the data durability on the magnetic tape and/or periodic tape scrubbing operations to enhance data durability on the magnetic tape.

A method for generating calibration data useful for calibrating a plurality of tape cartridges includes the steps of selecting a subset of tape cartridges from the plurality of tape cartridges, the subset of tape cartridges having fewer tape cartridges than the plurality of tape cartridges; calibrating each of the subset of tape cartridges using a plurality of tape drives to generate global calibration data; selecting one of the plurality of tape cartridges that is not included within the subset of tape cartridges; and calibrating the one of the plurality of tape cartridges using the global calibration data generated via the calibrating of each of the subset of tape cartridges.
