摘要： A method, computer system, and computer program product for determining head wear of magnetic tape head elements of tape drives during operation. The method may include receiving a first calibration parameter for a first tape head element at a first time. Calibration parameter for the first tape head element may be compared with a reference parameter. Determination may be made whether to remove the first tape head element from service or generate a warning, based on a result of the comparison. Method may include generating the first calibration parameter by calculating midpoint bias voltage for the first tape head element as a function of bias current and head resistance. The first calibration parameter for the first tape head element may be bias current parameter or bias resistance parameter. The first calibration parameter for the first tape head element may be less than, equal to, or greater than the reference parameter.

摘要： Some embodiments are directed to computer program products for use with tape drives that oscillate the relative transverse position of a tape and magnetic head during seek operations (for example, by moving the magnetic head in the transverse direction). Some embodiments are directed to methods and computer program products for use with tape drives that select relative transverse position of the tape and magnetic head to counter uneven wear (for example, observed uneven wear, uneven wear predicted based on historical tape and drive usage data).

摘要： A media device may comprise a controller, a tape head, a tape comprising tape-position indicia, an indicia detection device, and an adjusting device. The indicia detection device may be configured to detect the tape-position indicia and provide an output corresponding to a tape position. The controller may be configured to send an adjustment command based on the output. The adjusting device may be configured to adjust the media device between a first configuration and a second configuration, based on the adjustment command. The tape may physically contact the tape head in the first configuration and not physically contact the tape head in the second configuration.

摘要： A tape drive system with a transducer (for example, a magnetic head arrays/separation shield) located in a recess of a transducer housing (for example, supporting rails, a U-shaped carbon tape guide). During seek operations and/or data access operations (that is, read/write operations), the transducer and the transducer housing are moved, in the transverse direction relative to the direction of elongation of the tape, independently of each other. The motion of the transducer housing (for example, back and forth oscillatory movement in the transverse direction) is controlled to even out wear across the tape-facing surface of the transducer housing. Some embodiments accomplish this by using separate motors to transversely move the transducer and the transducer housing.

摘要： Embodiments of the present invention disclose methods, computer program products, and systems for replicating data stored on a tape cartridge on one or more computing devices. In one embodiment, initiation of a replication sequence begins in response to at least one of: receiving a manual prompt of a user, loading of a first tape cartridge to be replicated into a first tape drive, receiving a request from a backup program, or occurrence of a predetermined time. When priming a first tape cartridge for writing of data, the first tape cartridge is configured for replication to a second tape cartridge. After loading the first tape cartridge into a first tape drive, data stored on the first tape cartridge can be directly transmitted from the first tape drive to a second tape drive in which the second tape cartridge is loaded without using an intermediate host computer system to facilitate data transfer.
