摘要: A tape drive is disclosed. The tape drive determines a current tape width and writes data to the tape as well as the current tape width. The tape width written to the tape is associated with the data. When reading data from a tape the tape drive reads the stored tape width and adjusts the current tape width to match the stored tape width before reading the data associated with the stored tape width.

摘要: Servo pattern read-back signal processing for storage devices is described. In an example, a method of processing a read-back signal derived from a servo pattern on a storage medium in a storage device includes differentiating the read-back signal in an analog domain to produce a differentiated signal; and converting the differentiated signal into digital samples.

摘要: A system and method for positioning a sensor relative to a storage medium. A system includes a first sensor and a second sensor arranged so that a point of a storage medium traverses each sensor at a different time. A processor is coupled to the sensors. The processor varies the timing of a sample representing a noise signal received from the sensors in accordance with medium velocity. The processor adjusts the position of the sensors based on the sample.
