摘要： A control source and drivers for a thermal actuator fly height controlled heads in a disk drive system includes provisions for driving a heater element to dissipate various levels of power, and thus actuate the head by a desired amount, depending on whether the head is in a write mode or a read mode. Further, overshoot and undershoot are achieved as desired by providing initial values and equilibrium values and through the use of a control capacitor to provide a time constant to the drive signal to the heater element.

摘要： A RAID system is provided which can be implemented as a hardware RAID system while avoiding certain shortcomings of previous RAID systems. The RAID system makes it possible to avoid or reduce the number of buffers or processors and can take advantage of drive logic to achieve RAID functions or enhancements. RAID functionality can be provided in a manner to accommodate one or more ATA drive interfaces. To avoid drive replacement problems, host requests for drive serial numbers are responded to with a mirror serial number. In one embodiment, the read address is used to select which drive will perform a read operation.

摘要： A personal computer hard disk has disk media that comprises a primary portion and a backup portion; both portions are in the same hard disk housing. The backup portion is logically separate from the primary portion, and access to the logically separate backup portion is controlled by a backup access control mechanism. The backup access control mechanism may comprise a manually-actuable mechanism, such as a switch or a jumper, or it may comprise software provided in an ROM forming part of the internal memory of the hard disk.

摘要： A disk drive includes a rotatable storage disk, a suspension, and a slider assembly. The slider assembly includes a slider body, a first slider deformer and a second slider deformer. Activation of the first slider deformer deforms the slider body, and activation of the second slider deformer deforms the slider body. Further, the slider deformers can be independently controllable. The read element is positioned near the first slider deformer and the write element is positioned near the second slider deformer. Activation of the first slider deformer adjusts a read head-to-disk spacing of the read element and activation of the second slider deformer adjusts a write head-to-disk spacing of the write element. Further, activation of the first slider deformer does not significantly influence the write head-to-disk spacing and activation of the second slider deformer does not significantly influence the read head-to-disk spacing.

摘要： A method of determining side track erasure in a disk drive having a disk and a transducer. A target track and one or more side tracks proximate to the target track on the disk are selected, and recording parameters for recording signals on the target track and each side track with the transducer are selected. Thereafter, signals are recorded on each side track and then signals are recorded on the target track multiple times. A reduction in the integrity of the recorded signals on each side track due to recording signals on the target track multiple times is detected, and the detected reduction in the integrity of the recorded signals on each side track represents the amount of the erasure of the recorded signals on the side track. Recording parameters are changed based on the signal integrity reduction to minimize side track erasure.

摘要： A cellular telephone is configured to perform procedures to protect against malfunction or damage to an HDD or other mass storage device in the cell phone, in response to receiving an indication of an incoming call. The protection procedures can include delaying one or more cell phone operations, and/or sending instructions to an HDD or other mass storage device including instructions to complete an operation, suspend an operation, park a head and/or spin down an HDD. In a cell phone which provides for extended playback, e.g., of audio or video, the cellular telephone preferably is configured to avoid interruptions of playback, e.g., during suspension or HDD operation.

摘要： A PTP test subsystem of a magnetic disk drive identifies an undesired pole tip protrusion (PTP) condition, and takes steps to prevent problems associated with PTP. A PTP stressing mechanism stresses the disk drive during a PTP test mode to induce a PTP condition. A disk contact detection circuit detects when a head of the disk drive contacts the disk. A PTP write current determining circuit is also provided which comprises a write current level detector to ascertain a write current level at which the disk contact detection circuit detects when the head of the disk drive contacts the disk while the disk drive is stressed during the PTP test mode.

摘要： In accordance with various embodiments, a rotatable member is mounted to a spindle hub so that initial servo data previously provided to the rotatable member are eccentrically offset with respect to a rotational center of the spindle hub. Compensation vales are determined to characterize said offset, after which final servo data are provided to the rotatable member in relation to the initial servo data and the determined compensation values. The final servo data are nominally concentric with the rotational center of the spindle hub.

摘要： A method and apparatus for partial self-servo writing a disk surface in a disk drive using servo wedge propagation is provided. In one embodiment, servo information is written by a servo track writer near an outer diameter of the disk surface. The servo information is grouped into a 1× set of servo information and a 2× set of servo information. The disk drive's read head is used to read the 1× set of servo information in order to position the disk drive's write head to write servo information which is radially-aligned with the 2× set of servo information. Then, the disk drive's read head is used to read the 2× set of servo information in order to position the disk drive's write head to write servo information which is radially-aligned with the 1× set of servo information. The process is repeated on a track-by-track basis until servo information is written from the outer diameter of the disk surface to the inner diameter of the disk surface, as if it was entirely written by a servo track writer.

摘要： A method and apparatus for compensating for non-linearities due to pivot bearing friction when determining embedded runout correction values during partial self-servo write of a disk drive is disclosed. In one embodiment, the disk drive includes a disk surface having a track written thereon and the track has some written-in runout. The written-in runout that is associated with high-frequencies is determined using a first technique. The written-in runout for the track that is associated with low frequencies is determined using a second technique. Results from the two techniques are combined in order to determine embedded runout correction values for the track when partial self-servo writing, in order to reduce error propagation when writing additional tracks.
