摘要： In a state wherein an actuator (22) is located at a shunt position, when an apparatus is subjected to an external shock, the actuator (22) tries to swing due to a rotational moment. An inertia arm (7) generates a rotational moment simultaneously with the actuator (22). Both the rotational moments competes with each other at an engaging point of the inertia arm side with the actuator side to absorb the external shock. Further, the actuator (22) tries to excessively swing exceeding the limit of the original swing range during the operation of the apparatus. In order to prevent this, the inertia arm (7) is used.

摘要： A disk apparatus includes a disk (23) in which information is recorded, a carriage arm (26) having a head slider (27) provided at a tip thereof, the head slider moving over the disk during a read/write operation and being placed at an evacuated position outside an area of the disk during a halt of the disk apparatus, a support base, and a inertia latch mechanism (29) which slides on the support base (21) from an original position to a latch position in response to an impacting force so as to latch the carriage arm (26) when the disk apparatus is impacted, and slides on the support base (21) from the latch position to the original position by disengaging from the carriage arm (26) after dissipation of the impacting force, wherein the support base (21) and the inertia latch mechanism (29) are in contact with each other through at least one raised portion that prevents a single surface-to-surface contact from being dominant between the support base (21) and the inertia latch mechanism (29).

摘要： A method and an apparatus for controlling a disc drive, and more particularly, to a method and an apparatus for controlling a disc drive using a counter-electromotive force, which prevents collision and malfunction of a transducer and a disc by determining external vibrations and the magnitude of a shock without installing an additional shock sensor in a disc drive, are provided. The method for controlling a disc drive using a counter-electromotive force comprises (a) detecting a voltage applied to a voice coil during a predetermined mode, (b) performing an operation of the value of the counter-electromotive force using the voice coil voltage detected in (a), (c) comparing the value of the counter-electromotive force operated in (b) with a predetermined threshold, and (d) when the value of the counter-electromotive force is equal to or larger than the predetermined threshold, controlling a voice coil motor and a spindle motor so that a current mode is stopped and a parking or unloading mode is executed.

摘要： An information storage apparatus comprises a one or more storage media (168), which include a plurality of information tracks. Each storage medium (168) has a head assembly (170) having a substantially planar surface and a plurality of read/write heads positioned in registry with said information tracks. The read/write heads are arranged substantially in the plane of the planar surface. The information storage medium (168) and the head assembly (170) are arranged in mutually sliding abutment such that the read/write heads are substantially in sliding contact with the outer surface of the information storage medium in use.
In another aspect an information storage and retrieval apparatus comprises an information storage medium (168) comprising an information storage area, and an array (170) of information read and/or write heads. The information storage medium (168) and array of heads (170) are arranged to be oscillated with respect to each other in use such that each region of the information storage area is aligned with at least one of the read/write heads during the oscillation.-

摘要： A magnetic disk device (10) comprises a magnetic disk (11) in which a data zone (32) is formed. An actuator (22) has a voice coil (51) and a head slider (14) carrying a magnetic head, the actuator (22) being swung to move the magnetic head over the disk (11) between an innermost position (Pi) of the data zone and an outermost position (Po) of the data zone. A magnet has a magnetization center (58) and is opposed to the voice coil so that a voice coil motor (23) which swings the actuator is formed, the magnet having a north pole and a south pole confronting each other via the magnetization center. The magnetic disk device is provided so that a deviation of a center (C) of the voice coil (51) from the magnetization center when the magnetic head is in the innermost position of the data zone is substantially equal to a deviation of the center of the voice coil from the magnetization center when the magnetic head is in the outermost position of the data zone.
