To provide a disk drive system provided with an inertial latching mechanism which has high reliability and can be arranged in a thin-model disk drive system. There is provided an inertial arm (7) engaging an actuator (22) when a head arm (25) is in or near a parking position and releasing engagement with the actuator (22) when the head arm (25) is in or near a position close to a disk (1) and energizing means for holding a position of the inertial arm (7) in a position where the engagement with the actuator (22) is released. Even if a rotational shock is externally applied when the actuator (22) remains in the parking position, moment of rotation is applied on each of the actuator (22) and inertial arm (7) in the same direction, the actuator (22) and inertial arm (7) mutually restrain their operations at an engaging part, and the oscillation of the actuator (22) to a data area can be avoided. When loading, a position of the inertial arm (7) is held by the energizing means in the position where the engagement with the actuator (22) is released so that the release of the engagement and mode of operation of the engagement between the actuator (22) and inertial arm (7) when loading/unloading can be surely achieved.

Disclosed is an inertia latch mechanism capable of omitting erection of a pin for swinging an inertia lever. An inertia lever for use in the inertia latch mechanism is constituted of: a lever body swinging by inertia when an impact is applied thereto; a fixture fixed to a case of a disk drive device; and a plate spring member for connecting the lever body and the fixture and permitting swing of the lever body.

A disk apparatus includes a disk in which information is recorded, a carriage arm having a head slider 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 which slides on the support base from an original position to a latch position in response to an impacting force so as to latch the carriage arm when the disk apparatus is impacted, and slides on the support base from the latch position to the original position by disengaging from the carriage arm after dissipation of the impacting force, wherein the support base and the inertia latch mechanism 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 and the inertia latch mechanism.

A ramp assembly for loading and unloading of one or more sliders at the inner diameter of a disk drive. The disk drive has a base casting and one or more disk surfaces. The ramp assembly includes one or more projecting members, each projecting member including a disk-facing surface, a ramp which itself includes an inclined surface, a base member, which fastens to the base casting of the disk drive, and an upright member which connects the projecting member to the base member. A second embodiment is a double-sided ramp assembly including an upper projecting member and a lower projecting member, having two disk-facing surfaces and two ramps, each of which includes an inclined plane, a second upright member, a horizontal support member, and a connecting upright. A third embodiment uses multiple stories, where each double-sided ramp assembly is considered one story.

An actuator latch of a hard disk drive to lock an actuator so that the actuator does not rotate when a magnetic head installed at the actuator driven by a voice coil motor is positioned on a parking region. The actuator latch has: a locking protrusion installed at the actuator, a latch member rotatably installed on the basis of a predetermined rotation axis, the latch member rotating with the rotation of the actuator when the magnetic head is parked so that a hook intercepts the locking protrusion and prevents it from moving in an opposite direction to a parking side, and a latch member driving unit rotating the latch member to release the locking protrusion from the hook. The actuator latch of a hard disk drive selectively intercepts the movement of the locking protrusion at the actuator so that the actuator is locked and unlocked. The actuator can stay strongly locked and be softly unlocked without any impact.

A storage drive receives thereinto, retains, and ejects therefrom a removable storage media cartridge having storage media. The storage drive has an actuator including a carriage assembly with a head mounted thereto. The actuator moves the head as mounted to the carriage assembly with respect to the storage media of the retained media cartridge. The storage drive also has a head locking lever for locking the carriage assembly in a retracted position and unlocking same, and a multi-coil solenoid for actuating the head locking lever.

A low height disk drive having an overall height of approximately one inch (1null). The drive includes a head disk assembly, including a base plate, two disks rotatably supported on the base plate, a motor for rotating the disks, at least two heads for reading information from and writing information on respective ones of the disks; an actuator, supported on said base plate and responsive to control signals, for selectively positioning the heads with respect to the disks, and a cover sealably attached to the base plate to enclose the storage means, the head, and the actuator. The disk drive also includes control circuitry for generating control signals, and for providing information signals to and receiving information signals from the heads. The head disk assembly and the control circuitry have a combined height of approximately one inch or less.

In an actuator latch used with a hard disk drive to lock an actuator in a non-pivoting position when a magnetic head installed at the actuator is positioned in a parking zone of a hard disk, the actuator latch includes a hooked portion provided at one side of the actuator and having first and second hook steps disposed to face each other, a locking member having a hook portion which is coupled to the hooked portion as the actuator moves to the parking zone, the hook portion coupled to the hooked portion being interfered with the first hook step when the actuator rotate clockwise and with the second hook step when the actuator rotate counterclockwise, and an elastic member elastically supporting the locking member to be capable of rotating and providing a restoring force to the locking member with respect to both clockwise and counterclockwise rotations of the locking member. Thus, when a clockwise or counterclockwise rotational impact is applied to the hard disk drive, the actuator latch restricts rotation of the actuator so that the actuator cannot escape from the parking zone and the hard disk drive can be protected from being damaged.

A wired flexure comprises a substrate formed of an electrically conductive material, a read wire provided on the substrate so as to extend along the substrate, a write wire provided on the substrate so as to extend along the read wire, a slit formed between the read and write wires, etc. The slit extends along the read and write wires and divides the substrate between a first portion on the read wire side and a second portion on the write wire side. The slit is situated nearer to the read wire than to the write wire.

In a magnetic disk drive which comprises a magnetic head slider, a magnetic head slider support mechanism for supporting the magnetic head slider and moving it to a predetermined position, and a load/unload mechanism for detaching the magnetic head slider from the surface of a magnetic disk or moving it thereto, when the magnetic head slider is detached from the magnetic disk surface for unloading, the magnetic head slider support mechanism is restrained against displacement in at least one direction perpendicular to the magnetic disk surface by a restraining part which is provided at a position, on other than the load/unload mechanism, between the magnetic head slider and a pivot of the magnetic head slider support mechanism. Thus, it is possible to enhance impact resistance of the magnetic disk drive during non-ration.
