摘要： A disk drive is disclosed comprising a disk, a head for writing data to the disk, and control circuitry coupled to the head. The control circuitry is operable to determine a first set of fly height values and determine a threshold based on the first set of fly height values. The control circuitry determines a second set of fly height values, adjusts the threshold based on the second set of fly height values, and detects a head characteristic based on the adjusted threshold. The head characteristic is detected by detecting a head touchdown event and/or detecting contamination related to the head based on the adjusted threshold.

摘要： A disk drive measures the radial misposition of tracks and repositions the tracks at regularly spaced intervals. Written in runout (WRO) in servo bursts is determined to calculate track spacing and squeeze among adjacent tracks. Tracks with improper spacing are repositioned by adding a squeeze correction term to the servo wedges. Thereafter, when the disk drive operates to store data, the servo bursts are used to calculate a position error signal (PES), and the squeeze correction term is combined with the PES to position the head at a proper track radius.

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.
