摘要： A servo controlling method of the present invention is a servo controlling method for controlling a position of a magnetic head against a magnetic tape that is accommodated in a cartridge and has at least a data track and a servo track, and the method includes the steps of: reading tape variance information from a magnetic tape cartridge (23) side, the magnetic tape cartridge (23) being composed of a cartridge (20) and a magnetic tape (21); reading a servo signal recorded in the servo track by the magnetic head and converting the servo signal into head position information; and controlling the position of the magnetic head according to an off-track value based on the tape variance information and an off-track value calculated from the head position information. With this configuration, even in the case where a recording track width is narrowed and a tape speed is increased, the magnetic head can follow a recording track accurately at a high speed.

摘要： In the apparatus and method of the invention, a servo signal reproduction unit generates a PES from a servo signal reproduced from a magnetic tape, and a frequency conversion unit performs FFT processing of the PES to generate frequency component information. Then, a filter value generation unit generates filter values based on the frequency component information and writes these to a memory. When recording various data signals to the magnetic tape, the filter values are read from the memory and a control filter serving as a notch filter is incorporated into a feedback control for a tracking servo. This enables periodic and narrow-band noise to be removed from a PES, consequently reducing PESs. Accordingly, learning-type optimum notch filter control that allows a magnetic head to follow recording tracks at high speed and with high precision is possible even when the recording track width is reduced and the tape speed is increased.

摘要： A recording/reproducing method and a recording/reproducing device for magnetic tapes are less involved displacements between recording track and reproducing head even upon changes in the widthwise size of the magnetic tape, and capable of recording and reproducing data without causing errors, thus being ready for recording density enhancement of magnetic tapes. In both data recording and data reproduction, the tension of the magnetic tape is controlled so that absolute values of displacements between a pair of servo heads and a plurality of servo tracks corresponding to these servo heads are minimized.
