    摘要: The present invention provides a depopulation version hard disk drive apparatus that has a reduced number of magnetic heads and suspension arms from a standard hard disk drive apparatus, wherein the magnetic head can still be properly controlled during a loading state. The hard disk drive apparatus includes a ramp which interfaces with the suspension arm when loading and unloading the arm. An angle of a second slope surface 61c of the ramp in the depopulation version hard disk drive is set larger than that of the corresponding slope surface of the ramp 6 the a standard version hard disk drive.

    摘要: A head support assembly for a disk drive is comprised of a head suspension assembly connected to an actuator arm at one end and supporting a head at the other end, wherein a projection is formed on a flexure closely fixed on a thin-plate load beam, said projection projecting toward a disk surface and having a smooth surface. The projection is formed at a region somewhat close to the head supporting end from the hinge portion of the load beam. When shock is applied to the disk drive, bending occurs around the hinge portion of the load beam. During such bending, the projection having a smooth round surface is caused to contact the disk, whereby the disk surface is prevented from being damaged.

    摘要: An optical displacement measuring system using a triangulation comprises a light projecting unit for emitting to an object a light beam which is amplitude-modulated by a reference signal having a predetermined period, a light receiving unit for receiving light reflected back from the object and providing a pair of position signals, and a control signal generator for providing first and second control signals in synchronism with the reference signal. The position signals are processed by a switching unit in a time sharing manner according to the first control signal to obtain a first composite signal, in which the position signals occur alternately every integral number of the period of the reference signal. The first composite signal is amplified by a single amplifier at a desired amplification rate, and then sent to a distance determining unit, in which the polarity of the first composite signal is periodically reversed according to the second control signal to obtain a second composite signal, and a distance signal indicative of a distance between the light projecting unit and the object is determined from the second composite signal.
