  • Patent number: 7843662
    Abstract: A disk drive is disclosed comprising a first disk surface and a second disk surface, wherein the first disk surface comprises a plurality of concentric servo sectors extending across substantially an entire radius of the first disk surface. The concentric servo sectors are read across substantially the entire radius of the first disk surface using the first head to generate a read signal. The read signal is processed to generate a position error signal (PES) representing a radial location of the first head relative to the first disk surface. The PES is processed to generate a control signal applied to the VCM to move the second head radially over the second disk surface while writing a spiral servo track on the second disk surface.

  • Patent number: 7602575
    Abstract: A disk drive is disclosed comprising control circuitry for self servo writing a disk. An estimated reader/writer offset is initialized, servo bursts in a first servo track are read, the head is moved radially using the estimated reader/writer offset, and propagated servo bursts are written to a target servo track. The propagated servo bursts are read from the target servo track to generate a read signal, the read signal is processed to generate a burst crossing signal (BCS), and the estimated reader/writer offset is adjusted in response to the BCS.

  • Patent number: 7433143
    Abstract: A method and apparatus is disclosed for adjusting the track density by changing the slope of spiral tracks used to servo write a disk drive. A target track density is established for a disk surface, and a plurality of spiral tracks are written to the disk surface in response to the target track density. Each spiral track comprises a high frequency signal interrupted at a predetermined interval by a sync mark, and a slope of the spiral tracks is selected in response to the target track density. The head internal to the disk drive is used to read the spiral tracks in order to write product servo sectors to the disk to define a plurality of data tracks, wherein the slope of the spiral tracks determines the density of the data tracks.

  • Patent number: 7333280
    Abstract: A method of writing product servo sectors on a disk of a disk drive is disclosed. The disk comprises a reference pattern having a plurality of sync marks written around the disk. The sync marks are detected to generate a sync mark detect signal, and a timing recovery measurement is generated in response to the sync mark detect signal. A frequency control signal is generated in response to the timing recovery measurement, and a servo write clock is generated in response to the frequency control signal. A feed-forward compensation value is generated in response to the timing recovery measurement and the frequency control signal, and the timing recovery measurement is adjusted in response to the feed-forward compensation value to compensate for a repeatable phase error in the timing recovery measurement. The servo write clock and the head internal to the disk drive are used to write the product servo sectors to the disk.

  • Patent number: 7068459
    Abstract: A method and apparatus is disclosed for writing product servo sectors to a disk of a disk drive to define a plurality of data tracks. The disk drive comprises the disk and a head actuated over the disk. The disk comprises a plurality of spiral tracks which are read using the head to synchronize a write clock and to generate a position error signal (PES) according to a PES algorithm used to maintain the head along a first servo track while writing product servo sectors along the first servo track.

  • Patent number: 7050568
    Abstract: A method, system and product for managing a hold queue is provided. A call center receives an incoming telephone call from at least one caller and places the caller in an initial position in the hold queue. When a caller is in a hold queue at a call center, a request can be made to pause the caller's position in the hold queue. When the caller is ready to return to the hold queue or when the pause duration has expired, the caller becomes active in the hold queue.

  • Patent number: 6992852
    Abstract: A method is disclosed for reducing disk expansion effects while writing spiral reference patterns on a disk of a disk drive. The disk drive comprises control circuitry and a head disk assembly (HDA) for positioning a head radially over the disk. In the method, an external spiral servo writer is used to control a radial location of the head for writing a plurality of the spiral reference patterns between inner and outer seed tracks. A head velocity profile is adjusted for writing each spiral reference pattern to account for thermal disk expansion. The head internal to the disk drive is used to read the spiral reference patterns in order to write product servo bursts to the disk that define a plurality of radially-spaced circular data tracks.

  • Patent number: 6959081
    Abstract: A method, system, and program for expert hold queue management are provided. A call is received at a call center. The call is placed on hold in a hold queue until a representative of the call center is available to answer the call. While on hold in the hold queue, the call is transferred to an expert. In particular, the call may be transferred to a second hold queue within the first hold queue if the expert is not immediately available. Experts may include freelance experts, query based experts, and emergency response experts. Then, responsive to detecting the call at the top of the call queue, the caller is notified of an availability of a representative. The caller may select to remain with the expert or transfer to the representative.
