摘要： Disclosed is a magnetic disk apparatus constructed to reduce a track positional deviation of a magnetic head. This magnetic disk apparatus includes a rotary mechanism for rotating the magnetic disk and a rotary type actuator, provided with the magnetic head at its front end, which magnetic head has a write head and a read head, for moving the magnetic head in such a direction as to traverse tracks of the magnetic disk by making rotations about a rotary shaft. A distance A from the center of rotation of the rotary type actuator to the magnetic head is set equal to or larger than a distance B from the center of rotation of the rotary type actuator to the center of rotation of the magnetic disk. Even when separating a write element and a read element, the track positional deviation of the magnetic head can be reduced. This magnetic disk apparatus includes an enclosure accommodating both of a rotary mechanism and the rotary type actuator and having a base taking such a configuration that one side surface thereof is opened and a cover fitted in the base, wherein a side for separating the base and the cover is formed at a slant to a long side of the apparatus. This construction makes it possible to enhance a rigidity of the enclosure and reduce the track positional deviation of the magnetic head.

摘要： A magnetic disk apparatus includes a magnetic head, a magnetic disk, and a rotary actuator to move the magnetic head onto the magnetic disk. The rotary actuator includes a center shaft fixed to a disk enclosure, a carriage supporting the magnetic head and rotatably mounted to the center shaft, and a coil spring to return the carriage to a CSS zone when there is a breakdown or failure of the power supply of the magnetic disk apparatus. The coil spring is provided in a space formed between the center shaft and the carriage, and thereby can achieve a more compact magnet disk apparatus. Moreover, due to the assembly of the return coil spring around the shaft using a pair of end ring members, contact of the spring with the shaft and carriage is avoided and proper operation of the magnetic heads is ensured.

摘要： A gate driver mounted on a TCP is mounted on a print substrate. The input/output terminal, input terminal, and power terminal of the gate driver at one end of a group of gate drivers are connected to a controller by this mount, and a clock signal, select signal, and power voltage are transferred in a direction of the gate drivers. Meanwhile, the input terminal of a gate driver at the other end of the group of gate drivers is connected to the controller, and a start pulse signal is transferred in a direction of the gate drivers. As a result, it is possible to provide a display driving device in which a start pulse signal is fed in at a correct timing, a manufacturing method thereof, and a liquid crystal module employing such a display driving device.
