  • Patent number: 8335049
    Abstract: A disk drive is disclosed comprising a first disk surface, a first head coupled to a distal end of an actuator arm, and a voice coil motor (VCM) and a first microactuator operable to actuate the first head over the first disk surface. A servo loop for servoing the head in response to the servo sectors is disabled, and after disabling the servo loop, the first microactuator is excited with a control signal at a test frequency in order to accentuate a crack in the first microactuator. After exciting the first microactuator, the servo loop is enabled, and after enabling the servo loop, the first microactuator is evaluated to detect the crack in the first microactuator.

  • Patent number: 8330741
    Abstract: Methods, Integrated Circuits (IC) and computer programs for decoding contacts in a digital resistive screen overlay (DRSO) are presented. The method includes coupling in succession columns of the DRSO to a first voltage while floating a remainder of the columns. Further, the method includes the operation of checking during a sampling time if each row of the DRSO is connected through closed switches in the DRSO to the column coupled to the first voltage. The sampling time is configured such that the sampling time for a given row is previous to the arrival time of a signal that started with the coupling of a column and that propagated to the given row through more than one closed switch in the DRSO.

  • Patent number: 8325437
    Abstract: There is provided an image recording/reproducing device that can discriminate a disk separation error that is specific to removable hard disks. A disk error detector (51) detects an occurrence of a disk error depending on whether a removable hard disk (15) can be recognized or not. A mount status detector (55) detects a presence or absence of the removable hard disk (15) as a disk mount status. The mount status detector (55) may detect the disk mount status based on a detection result of a write-protect switch (19) of the removable hard disk (15). An error type discriminator (57), based on the detected disk mount status, discriminates an error type of the disk error, and determines that the error type is disk separation if the removable hard disk (15) has become nonexistent. An error handler (59) performs error handling in accordance with the error type discriminated by the error type discriminator (57).

  • Patent number: 8315008
    Abstract: According to one embodiment, a magnetic disk device includes a magnetic disk, a magnetic head, a position error signal output module, a vibration pattern detector, an adder, and a head positioning controller. The magnetic head moves over the magnetic disk. The position error signal output module outputs a position error signal based on a difference between a head position of the magnetic head over the magnetic disk and a target position on the magnetic disk. The vibration pattern detector detects a vibration pattern of the magnetic head caused by vibration. The adder adds the position error signal to an offset signal indicating amplitude of the vibration pattern. The head positioning controller moves the head position to the target position based on a result of addition by the adder.

  • Patent number: 8315134
    Abstract: A disk has a plurality of recording layers in a laminated direction. When a defect occurs in any one of recording layers during disk manufacture, information about the defect is recorded in a read-only region in the recording layer. An optical disk apparatus determines which of the recording layers is usable based on the information about the defect read from the disk, and executes a recording/reproducing operation according to a determination result. Therefore, even when a disk with a defect in the recording layer is used, that disk may be offered to a user as an appropriately usable disk.
