摘要： Data is recorded such that the positions of data will be aligned in a traveling direction and a width direction of the storage medium. The medium travels in the traveling direction from a first to a second position as a certain wrap of a group of plural files in a first physical range between the first and the second positions. A head shifts from the certain wrap to another wrap in the width direction of the medium. The medium travels in the traveling direction from a third to a fourth position as the other wrap of a group of plural files in a second physical range between the third and the fourth positions. The plural files in groups on the certain wrap and the other wrap may be written in reverse order to each other after being once stored in a buffer.

摘要： According to one embodiment, a system includes a controller configured to determine whether a position error signal (PES) is invalid while reading data from a magnetic medium using at least one data channel. An invalid PES indicates off-track reading or a defect in the magnetic medium. The controller is also configured to determine whether a PES value is above a first predetermined threshold in response to a determination that the PES is valid. Moreover, the controller is configured to inject error bits into a data stream in place of corresponding bits of decoded data in response to a determination that the PES is invalid, a determination that the PES value is above the first predetermined threshold, or a determination that the PES is invalid and the PES value is above the first predetermined threshold.

摘要： Provided are a computer program product, system, and method for determining a skew error signal (SES) offset used to determine an SES to adjust heads in a drive unit. A determination is made of a first difference in a first orientation with respect to a direction of movement of the recordable storage media based on first and second position information read by first and second servo read elements on a first head. A determination is made of a second difference in a second orientation with respect to the direction of movement of the recordable storage media based on third and fourth position information read by the first servo read element and a third servo read element on a second head. An offset, calculated based on the determined first and second difference, is used to generate an error signal to adjust the first and second heads.

摘要： A method according to one embodiment includes detecting a signal originating from at least one reader of a first outer module of a head as a tape passes thereacross, the head having at least the first outer module and a second outer modules positioned on opposite sides of an inner module and aligned with the inner module in a direction of tape travel thereacross. A first guide positioned in front of the first outer module is moved in a direction towards the tape until the signal detected by the first outer module decreases. The first guide is moved in a direction away from the tape to a position to set about a predetermined wrap angle of the tape relative to the first outer module after the signal detected by the first outer module decreases.
