摘要： The method employs a servo system for positioning a head laterally to follow lateral motion of a longitudinal tape having longitudinal defined servo track(s), the servo system comprising a servo element configured to sense lateral position of the head with respect to an acquired servo track, a fine actuator configured to translate the head laterally with respect to the longitudinal tape, and a position error signal loop to operate the fine actuator to translate the head laterally to reduce position error. If the servo element is positioned away from the defined servo track(s), a continuous position error offset signal is applied to the fine actuator in a direction towards the defined servo track(s), whereby the fine actuator translates the head in accordance with the continuous position error offset signal; and, in response to the servo system acquiring the defined servo track(s), the continuous position error offset signal is discontinued.

摘要： Methods, magnetic tape data storage drives, data storage systems, and magnetic tape data storage cartridges. A system having at least one magnetic tape data storage drive is configured to handle a magnetic tape cartridge comprising a magnetic tape data storage media and accompanying cartridge memory. The magnetic tape media comprises a plurality of longitudinal servo bands, the servo bands separated by data bands. Two servo bands, each at opposite sides of a data band are sensed. In response to at least one servo detection error signal of one of the two servo bands, an edge stress signal is set to the cartridge memory of the magnetic tape cartridge. Then, for example, after reloading the cartridge, the cartridge memory is inspected for a set edge stress signal; and, if the edge stress signal is set, only read operations are allowed with respect to the inspected magnetic tape data storage cartridge.

摘要： In one embodiment, a tape read/write head supported by a lever is biased in a first position, using magnetic attraction between a magnet supported by the lever, and a return path structure of magnetically permeable material. In the illustrated embodiment, the magnet centers itself, in the absence of a coil generated magnetic field, in the middle of a gap of the magnetic return path structure. In one aspect, the mass of the read/write head and one side of the lever may be balanced by the mass of the magnet and the other side of the lever. The lever and hence the tape read/write head carried by the lever, may be pivoted by conducting current through a coil to generate a magnetic field which is conducted by the return path structure to interact with the magnetic field of the magnet. As a consequence, the lever pivots on a pivot axis as a function of the magnitude and direction of the current through the coil. The face of the magnet may be divided into portions of opposite magnetic polarity to facilitate a relatively pure torque to be developed substantially without a net force. Other embodiments are described and claimed.

摘要： Dynamic calibration of a secondary velocity signal is provided in a tape drive. In one example, a reel motor is operated to drive a reel carrying a tape in a tape drive. The motion of the tape is measured to provide a measured primary velocity signal of the tape, and in addition, the operation of the reel motor is measured to provide an estimated secondary velocity signal of the tape as a function of motor parameters and the motor operation measurements. The estimated secondary velocity signal of the tape may be calibrated as the tape is driven, as a function of the tape motion measurements and the motor operation measurements. Other embodiments are described and claimed.
