A magnetic tape cartridge includes a magnetic tape, and a storage medium in which information on the magnetic tape is stored. The magnetic tape has a recording surface. Data is recorded in the recording surface by a magnetic head in a state in which the magnetic tape is made to travel. The magnetic head is disposed at an inclined posture with respect to a width direction of the magnetic tape along the recording surface. Angle adjustment information obtained at a data recording timing which is a timing at which the data is recorded in the recording surface is stored in the storage medium. The angle adjustment information is information for adjusting an angle at which the magnetic head is inclined with respect to the width direction along the recording surface.

A rotary actuator for positioning a recording head in a data storage mechanism and that includes first and second cylindrical subassemblies separated by an air gap. One of the subassemblies includes a magnetically conductive core with an electrically conductive coil wrapped thereover to enable first and second current flow directions in the circuit. The other of the subassemblies includes a magnetically conductive core and at least one magnet secured thereto. Transmission of an electric current through the electrically conductive coil induces rotation of one of the subassemblies relative to the other of the subassemblies to rotate the recording head about an axis that is perpendicular to recording media on the recording head. The disclosed rotary actuator facilitates quick and accurate recording head position changes due to low inertia of the rotating subassembly as well as reduced inductance and symmetrical mass distribution of the actuator.
