    摘要： A disk drive for storing data includes a drive housing, a storage disk that is rotatably coupled to the drive housing, a slider assembly positioned near the storage disk, and a drive circuitry. The slider assembly includes a head that interacts with the storage disk during a data transfer operation. The drive circuitry performs a performance test on the head at a first HtD spacing and at a second HtD spacing that is different than the first HtD spacing while the drive is operation. The slider assembly includes a slider mover that moves the head between the first HtD spacing and the second HtD spacing. The slider mover can move the head to the first HtD spacing during the data transfer operation if the result of the performance test is a first test result and the slider mover moves the head to the second HtD spacing during the data transfer operation if the result of the performance test is a second test result.

    摘要： A method for manufacturing a first disk drive includes incorporating a first storage disk having a first storage surface, and a first slider having a first read/write head and a slider mover into the first disk drive. Further, the first read/write head is movably positioned a first head-to-disk spacing relative to the first storage surface. The method also includes determining an incremental power level necessary to be delivered to a second slider mover of a second slider having a second read/write head to adjust a second head-to-disk spacing relative to a second storage surface by a predetermined increment. In addition, the method includes adjusting a first head-to-disk spacing by directing an operational power level to the first slider mover. The operational power level is derived from the incremental power level. The step of determining an incremental power level can include directing power to the second slider mover and detecting approximately when a portion of the second slider first contacts the second storage surface. Moreover, the step of adjusting can be performed during one or more manufacturing operations of the first disk drive.

    摘要： A disk drive includes a drive housing, a storage disk, a slider and a drive circuitry. The storage disk has an inner and an outer diameter. The slider includes a read/write head and a slider mover that receives power from the drive circuitry to position the read/write head at a predetermined head-to-disk spacing during radial movement of the slider relative to the storage disk. The drive circuitry can direct a varying level of power to the slider mover during radial movement of the slider. In addition, the drive circuitry can increase the power to the slider mover as the read/write head nears a target track in order to decrease the head-to-disk spacing at the appropriate time. The drive circuitry can adjust the power to the slider mover so that the head-to-disk spacing remains within a predetermined range as the slider moves radially relative to the storage disk. The drive circuitry can also direct power to the slider mover so that the head-to-disk spacing is substantially the same at the start of a seek operation and when the read/write head arrives at a target track. The drive circuitry can also direct power to the slider mover based at least partially on the temperature of a portion of the slider.

    摘要： A disk drive is disclosed comprising a head actuated over a disk comprising a plurality of tracks. Data is read from a target track, and an off-track read capability (OTRC) is generated for a plurality of segments of the target track. For example, an OTRC may be generated for a plurality of data sectors, wherein the combined OTRCs may be evaluated to compute an average track center, or an average track width, or a repeatable runout (RRO).

    摘要： A disk drive having a drive housing, a storage disk that is rotatably coupled to the drive housing, and a slider assembly that includes a head and a slider mover. The head reads data from the storage disk during a read operation and writes data to the storage disk during a write operation. The slider mover maintains the head at a read HtD spacing during the read operation, at a pre-write HtD spacing during the read operation prior to the write operation, at a write HtD spacing during the write operation, and at an idle HtD spacing when the drive is not performing the read operation or the write operation. The disk drive includes a drive circuitry that directs a read power level to the slider mover to maintain the head at the read HtD spacing, a pre-write power level to maintain the head at the pre-write HtD spacing, a write power level to maintain the head at the write HtD spacing, and a idle power level to maintains the head at the idle HtD spacing.
