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.

摘要： Each servo disk is formed by obtaining an angle from a stopper space obtained by moving an actuator, further obtaining a feed pitch angle for each cylinder by a prespecified number of cylinders from the angle, and writing servo data thereon according to the pitch angle, so that a feed pitch angle becomes larger in association with a wider space between the stoppers, with which a larger track pitch for each cylinder can be insured.

The rotary actuator includes an actuator arm assembly rotatably mounted on a base of the magnetic disk drive, an FPC mounted on one side surface of the actuator arm assembly, and a magnetic circuit constituting a voice coil motor by combination with a moving coil supported to the actuator arm assembly. A retractor plate is fixed to the actuator arm assembly at a position opposite to a mounting position of the FPC with respect to the center of rotation of the actuator arm assembly. The retractor plate functions to retract the magnetic heads to the CSS zone of the magnetic disks by magnetic reaction with a magnetic flux in the magnetic circuit.
