    • In the memory management method, when a failure is detected in the power supplied to a protective memory, a control toward the memory is cut off from a CPU and the power supply is switched to a standby power before the protective memory has some damaging effect; after solution of the power failure, the switching is finished, the control toward the memory is returned to the CPU, and the power supply is returned to an ordinal one; write completion of data is notified to the client at a time when the data sent from the client has been written into the protective memory; whether the last termination is abnormal or normal is checked at the activation; when the last termination is abnormal, the protective memory is returned after memories other than the protective memory are initialized at the activation; and when the last termination is normal, the protective memory is returned and thereafter all the memories are initialized at the activation.

    • 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.

    • 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.
    • 本发明涉及一种用于磁记录装置的磁头机构控制装置,其确保在磁头卸载操作中已经卸载了传感器头。 具有换能器头的头部滑块安装在头臂上,并通过头臂的摆动从盘上卸载。 缩回位置在头臂的摆动范围的极限部分。 当头滑块成功地卸载到缩回位置时,在卸载方向上施加到头臂的驱动力导致头臂几乎没有移动。 在执行卸载之后,向头臂施加位置检查驱动力,并且检测磁头滑块的移动速度。 基于移动速度,判断磁头滑块是否卸载到缩回位置。 如果磁头滑块未卸载到缩回位置,则执行重新卸载以将磁头滑块移动到缩回位置。
