摘要： A disk drive detects head touchdown based on a magnitude of a position error signal at a discrete frequency. The discrete frequency is one-half the disk rotation frequency or an integral multiple of the disk rotation frequency. The head is heated by turning on a heater at the discrete frequency, thereby injecting bias into a servo system that increases the PES magnitude. In addition, the servo system has a first transfer function for tracking the head during read and write operations and a second transfer function for tracking the head during head touchdown detection. The second transfer function has smaller vibration rejection than the first transfer function so that the disk drive is less sensitive to vibration during read and write operations than during head touchdown detection.

摘要： Methods of compensating for repeatable runout in a disk drive are provided. The disk drive includes a data storage disk, a transducer adjacent to the disk, a primary actuator for positioning the transducer over a first range of movement, and a secondary actuator for positioning the transducer over a second range of movement that is less than the first range of movement. Estimates are made of the position of the secondary actuator in the second range of movement. Data is read from the disk via the transducer. A position error signal is determined based on the read data. Positioning of the transducer by the primary actuator is controlled based on the estimated position of the secondary actuator in the second range of movement and based on the position error signal to compensate for repeatable runout.

摘要： A method and apparatus for determining embedded runout correction values when self-servo writing or partial self-servo writing is disclosed. In one embodiment, a disk surface, which has servo information written thereon, is provided. The servo information is grouped into 1x servo sectors and 2x servo sectors, and the 1x servo sectors and the 2x servo sectors form a plurality of tracks. A read head servos on the 1x servo sectors associated with a track. Both position error signals due to repeatable runout for the 1x servo sectors and information related to position error signals due to repeatable runout for the 2x servo sectors are determined, while servoing on the 1x servo sectors. Embedded runout correction values for the 1x servo sectors and the 2x servo sectors are calculated.

摘要： A reduction in computational load associated with correction of repeatable runout is provided. Rather than performing DFT for each analyzed frequency at each interrupt, at least some frequencies are not analyzed in the same interrupt period. DFTs for different frequencies may be staggered or interleaved. DFTs for different frequencies may be performed at different rates, preferably, using higher rates for higher frequencies.

The pad area includes a substrate having a first metal layer above it. A second metal layer is below the first metal layer. The active device resides in the substrate below the second metal layer. A layer of dielectric separates the first and second metal layers. A via within the dielectric layer electrically couples the first and second metal layers. A via connects to the active component. Subsequent metal layers can be arranged between the first and second metal layers.

摘要： A disk drive uses seek profile manipulation to provide enhanced transducer fly height control. The maximum seek velocity that is used during a seek operation is made dependent upon, among other things, the direction associated with the seek operation (i.e., either radially inward or radially outward with respect to the disk). In a preferred embodiment, the maximum seek velocity in a direction that normally results in a fly height loss is made less than the maximum seek velocity in the opposite direction. Thus, a minimum transducer fly height can be maintained with minimal effect on average seek time in the disk drive. In one approach, the maximum seek velocity values are stored within a lookup table within the disk drive.
