In a tape drive for storing and retrieving information to and from a media, a system for optimizing write performance includes a tape head and a controller. The tape head may include a write element. The controller may be for optimizing write performance in response to at least one media information signal that is stored on a media cartridge.

System and method for read/write optimization

An apparatus includes a tape read head bias signal control circuit configured to present to a tape read head a first amplitude bias signal in response to at least a first control signal and a second amplitude bias signal in response to at least a second control signal, wherein the second amplitude is lower than the first amplitude. The read head, thereby, may have a reduced operating temperature.

Servo tracks combine low frequency transitions for fine transverse positioning with high frequency fields providing additional information. In one embodiment, each servo frame has a first field of recorded low frequency transitions, a second field of recorded low frequency transitions, and at least one high frequency field. The first low frequency field transitions are recorded on the tape such that a peak of each first field transitions varies in longitudinal position across the width of the servo frame. The second field of low frequency transitions are recorded on the tape such that a peak of each second field transition is not parallel with the peak of any first field transition. High frequency fields may provide one or more of timing information, longitudinal position information and gross transverse position information.
