摘要： A servo pattern recording device capable of improving the recording accuracy of a servo pattern. The servo pattern recording device is comprised of a magnetic head that records a servo pattern for tracking servo on a magnetic tape, a first motor that feeds the magnetic tape, a second motor that takes up the magnetic tape, and a main panel along a surface of which the magnetic tape is caused to move. The first motor and the second motor are mounted on the main panel, and the magnetic head is mounted on a first sub panel that is formed separately from the main panel and is connected to the main panel via a connecting member.

摘要： A head apparatus includes: a head unit where a plurality of magnetic elements, which carry out reproducing and/or recording on data tracks on a magnetic tape, are disposed at equal intervals on a first straight line; a moving mechanism that moves the head unit; and a controller that carries out tracking control to cause the moving mechanism to move the head unit and keep the magnetic elements on the data tracks. The moving mechanism can rotate the head unit so as to increase or decrease an angle between a second straight line along a width of the magnetic tape and the first straight line. During tracking control, the controller causes the moving mechanism to rotate the head unit so as to increase or decrease the angle in accordance with changes in an interval between the data tracks and keep the respective magnetic elements on the respective data tracks.

摘要： A burst interval measuring apparatus includes: a detector that outputs detection signals that can to measure a burst interval of servo patterns for a tracking servo; and a measuring unit that measures the burst interval based on the detection signals. The detector is constructed so as to be capable of outputting the detection signals that can measure the burst interval at plural positions that are separated in a width direction of the magnetic tape inside one of the servo patterns. The measuring unit uses measurement values for the burst interval at at least two positions out of the plural positions that have been measured based on the detection signals to specify velocity fluctuations in a movement velocity of the magnetic tape in the length direction and corrects the measurement values based on the velocity fluctuations.
