  • Patent number: 8941944
    Abstract: A method of radially positioning a heat assisted magnetic recording (HAMR) head writes data to a first band, wherein a radial position of the HAMR head within each data track is defined by a positional bias and a track location. A determination is made regarding whether a threshold has been reached with respect to the first band. If the write threshold has been reached with respect to the first band, then the positional bias associated with the first band is modified to evenly distribute thermal exposure of data tracks in the first band.

  • Patent number: 8721903
    Abstract: A vacuum planarization method substantially improves the surface roughness of a thermally-assisted recording (TAR) disk that has a recording layer (RL) formed of a substantially chemically-ordered FePt alloy or FePt-X alloy (or CoPt alloy or CoPt-X alloy) and a segregant, like SiO2. A first amorphous carbon overcoat (OC1) is deposited on the RL and etched with a non-chemically reactive plasma to remove at least one-half the thickness of OC1. Then a second amorphous carbon overcoat (OC2) is deposited on the etched OC1. The OC2 is then reactive-ion-etched, for example in a H2/Ar plasma, to remove at least one-half the thickness of OC2. A thin third overcoat (OC3) may be deposited on the etched OC2.

  • Patent number: 8622646
    Abstract: An electronic device includes a frame defining a slot and a first through hole, a slot cover moveably received in the slot, a latching member rotateably connected to the frame, and a torsion spring. The latching member includes a first arm and a second arm protruding therefrom and extending in opposite directions. When the latching member is at a locking position, the first arm faces the first through hole, and the second arm engages an elastic hook to retain the cover in the slot. The spring includes a first arm fixed to the first arm and a second arm fixed to the frame. The latching member is driven to rotate when the first arm is pushed by an elongated object passing through the first through hole, causing the second arm push the elastic hook to be deformed, thereby allowing the second arm to disengage from the elastic hook.

  • Publication number: 20130278512
    Abstract: A touch-sensitive electronic device includes a touch screen receiving and responding to touch operations, and obtaining the location of the touch operations; a display; a memory; and a processing unit, to run a program to activate a clipping module. When the clipping module is activated, the device enters into a clipping mode. In the clipping mode, an image is formed which is the same as the content displayed on the display. The clipping module includes a detection sub-module to detect the touch operations on the formed image in the clipping mode to determine a track of the touch operations. An obtaining sub-module determines a desired area enclosed by the track on the formed image, and obtains the content in the desired area as the object to be clipped; and a storing sub-module stores the object to be clipped in the memory. A clipping method is also provided.

  • Patent number: 8481245
    Abstract: A pattern clean-up for fabrication of patterned media using a forced assembly of molecules is disclosed. E-beam lithography is initially used to write the initial patterned bit media structures, which have size and positioning errors. Nano-sized protein molecules are then forced to assemble of on top of the bits. The protein molecules have a very uniform size distribution and assemble into a lattice structure above the e-beam patterned areas. The protein molecules reduce the size and position errors in e-beam patterned structures. This process cleans the signal from the e-beam lithography and lowers the noise in the magnetic reading and writing. This process may be used to fabricate patterned bit media directly on hard disk, or to create a nano-imprint master for mass production of patterned bit media disks.

  • Patent number: 8432682
    Abstract: An electronic device includes a housing defining a slot, a card socket, a slot cover moveably received in the slot, and an elastic piece. The card socket is capable of ejecting an electronic card out when pressed. The cover defines a through hole and an elastic hook engaging the slot to retain the cover in the slot. The elastic piece includes a base facing the first through hole, and a pair of arms connected to opposite ends of the base and abutting against the cover. The elastic piece is urged to be deformed to push the cover when the base is pushed by an object passing through the through hole, causing the hook to disengage from the slot. Then the base pushes the card to move inwardly, causing the card socket to push the card and the cover to move out of the slot in union.
