摘要： The present invention provides a disk drive, a loading/unloading apparatus, and a method for controlling the apparatus, capable of improving the reliability of data by performing stable speed control. A disk drive comprises a VCM spindle driver for rotating a disk, a magnetic head, an actuator mechanism for moving a head slider having the magnetic head to a position above the surface of the magnetic disk and an unloaded position, a ramp block, and a CPU/HDC for performing the speed control of an actuator and the calibration control for detecting the offset and dynamic range of an AD converter before the speed control and controlling the operation for reading or writing data from or into the disk, which increases a rectangular current value to be applied to a voice coil while successively changing codes, measures an offset in accordance with the AD converter value for each current value, and moreover measures a dynamic range by deciding a nonlinear area when the difference between the expected value and measured value of the AD converter becomes a predetermined value or more.

摘要： The invention relates to a head mechanism control apparatus for magnetic recording device which ensures that the transducer head has been unloaded in a head unloading operation. A head slider having a transducer head is mounted on a head arm and is unloaded from the disk by the swinging of the head arm. The retract position is at the limit portion of the swingable range of the head arm. When the head slider is successfully unloaded to the retract position, a drive force applied to the head arm in the unload direction causes little movement of the head arm. After an unloading is performed, a position check drive force is applied to the head arm and the moving speed of the head slider is detected. Based on the moving speed, it is judged whether the head slider has been unloaded to the retract position. If the head slider has not been unloaded to the retract position, re-unloading is performed for moving the head slider to the retract position.

摘要： A disk drive with means to prevent accidental landing of a head/slider on the disk surface is described. In one embodiment a shock sensor is provided to sense external shocks received by the mechanism. During loading (positioning) of the actuator bearing the head/slider over the disk, if a shock is sensed, loading is stopped and an immediate unloading is performed to return the actuator to the withdrawn position. In another embodiment the unload operation is performed when the rotational speed of the disk is changed. In another embodiment the unload operation is performed when the rotational speed of the disk drops below a threshold. A circuit and method for detecting when the rotational speed of the disk drops below a threshold is also provided. The unloading in the various embodiments may be performed using velocity control or without velocity control.

摘要： The invention relates to a magnetic recording device which can be used at a reduced atmospheric pressure without having the head/slider assembly stick to the disk. A method of the present invention for controlling the operation of a disk drive device in reduced atmospheric pressure where a read/write head mounted on a head support arm flies above the surface of a rotating recording disk. The head support arm is moved along a radial direction of the recording disk to position the read/write head to one of cylinder positions of the recording disk. The method comprises steps of (i) detecting a value of the reduced atmospheric pressure during a power on reset period before a read/write period, (ii) storing information indicating whether the detected value of atmospheric pressure is lower than a threshold value, and (iii) accessing, during the read/write period, the stored information to determine whether an operation for lowering a flying height of the read/write head to a height which is lower than a height for the read/write operation should be inhibited.

摘要： Location positioning setting information is read from a setting storage section when the user depressed a power key. The location positioning setting information comprises setting information, such as the maximum duration time of the location positioning operation and the operation timing when a power-off event has been generated. A control section turns off the power of a display section, a speaker, a microphone, etc., excluding a communication function for transmitting location positioning and positioning results. In this state, a location positioning section acquires the positional information of the mobile communication terminal. Then, a wireless communication section transmits the location positioning information of the positioned mobile communication terminal to a predetermined monitoring server which manages the positional information of the mobile communication terminal.
