| 发明名称 | Skew estimation for a tape storage device | ||
| 摘要 | An apparatus for operating a tape storage device comprises a tape skew estimation unit for estimating a value related to a skew of a tape storage medium arranged in the tape storage device relative to a head module of the tape storage device. A servo pattern decoder is configured to decode information encoded in a servo pattern written to one or more servo bands of the tape storage medium based on read-back signals of at least two servo readers of the tape storage device arranged for reading the servo pattern from the one or more servo bands and based on the estimated skew related value. | ||
