摘要： A disk drive comprises a disk drive base, an actuator rotatably coupled to the disk drive base, a magnet disposed adjacent the actuator, and a latch. The latch is coupled to the disk drive base. The latch includes a latch body, a retention bore, a seating cavity, and a biasing ball. The retention bore extends into the latch body along a bore longitudinal axis. The retention bore includes a ball entrance defining a ball entrance diameter. The seating cavity extends from within the retention bore into the latch body. The seating cavity has an interior dimension perpendicular to the bore longitudinal axis greater than the ball entrance diameter. The biasing ball is disposed at least partially in the retention bore and at least partially within the seating cavity. The biasing ball comprises a magnetic material and has a ball diameter greater than the ball entrance diameter.

摘要： A novel actuator latch includes a catch portion interfering with actuator rotation with the latch in a closed position. The latch includes a first stop portion that is in contact with a fixed member with the latch in the closed position. The latch includes a pusher portion that is in contact with the actuator with the latch in the closed position and with the actuator in an extreme rotational position. The pusher portion has a torsional stiffness about the latch pivot location in the range 5 JA/rad·sec2 to 30 JA/rad·sec2, where JA is the rotational inertia of the actuator about the actuator pivot location expressed in units of kg·m2. The first stop portion has a torsional stiffness about the latch pivot location that is at least 5 times that of the pusher portion.

摘要： A disk drive includes a ramp having a fixed portion that is fixed to the disk drive base, and a guide portion that is not. The guide portion includes a guide surface having a parking region that is in contact with an HGA lift-tab with the disk drive in a non-operational state. The guide surface also has a load/unload region that extends over a disk outer periphery. The guide surface defines a guide surface length that is measured from the parking region to the load/unload region. The ramp also includes a torsionally-compliant member connecting the fixed portion to the guide portion. A distance between the torsionally-compliant member and the parking region, measured approximately parallel to the guide surface length, is less than half the guide surface length. The guide portion is not connected to the fixed portion over at least two-thirds of the guide surface length.

摘要： A disk drive having a translatable ramp is disclosed. The disk drive includes a head gimbal assembly having a proximate end that is attached to an actuator, and a distal end that includes a lift tab. The ramp includes a lift tab supporting surface located as close to a pivot axis of the actuator as is the lift tab. The ramp also includes a ramp guiding surface that is in contact with a mating surface of the disk drive base. A fastener selectively allows or prevents relative translation between the ramp and the disk drive base. The aforementioned contact constrains the relative translation so that the relative translation changes the distance between the lift tab supporting surface and the disk axis of rotation more than the relative translation changes the distance between the lift tab supporting surface and the actuator pivot axis.

摘要： A device for providing an external display and keypad for a smart-phone. The device has a port for receiving the smart phone. The device does not have its own computing power, but uses the computing power of the smart phone itself, thereby allowing the device to be smaller, lighter and less expensive than a standard lap-top computer not notebook device. The device is configured with a port for receiving a smart-phone and preferably holds the smart phone so that does not extend above the surface of the device or is flush with the surface of the device. The device can also be configured to allow the smart phone itself to act as a numerical keypad adjacent to the keypad provided on the device.

摘要： A method of manufacturing of a hard-disk drive using a bulk eraser for erasing recorded information on a magnetic-recording disk. The method includes providing a bulk eraser that produces magnetic-flux density in a gap sufficient to erase recorded information from a magnetic-recording disk, a hard-disk drive, a disk-stack having at least one magnetic-recording disk, and a drive motor for rotating the magnetic-recording disk. The method also includes configuring a plurality of magnets and a structure of the bulk eraser such that magnetic-flux density is oriented parallel to and in a radial direction of the magnetic-recording disk; and rotating the magnetic-recording disk. The method further includes inserting the hard-disk drive into the gap of the bulk eraser; and erasing recorded information from the magnetic-recording disk located in the gap; and removing the hard-disk drive from the gap.

摘要： A bulk eraser for erasing recorded information on a magnetic-recording disk. The bulk eraser includes at least three magnets and a structure magnetically coupled with the at least three magnets to produce magnetic-flux density in a gap. The gap has a first portion, a second portion and a third portion, such that a first magnet and a second magnet are disposed with opposing end poles across the first portion. The at least three magnets and the structure are configured to produce a magnetic-flux density in the second portion sufficient to erase recorded information from a portion of at least one magnetic-recording disk in a disk-stack when a hard-disk drive is inserted into the second portion. In addition, the at least three magnets and the structure are configured to direct the magnetic-flux density in a substantially radial direction of the portion of the magnetic-recording disk in the second portion.
