  • Magnetic recording disk and disk drive with alternating single-polarity position error signal (PES) blocks for read/write head positioning
    Patent number: 7986488
    Abstract: A magnetic recording disk drive has a position-error-signal (PES) servo pattern divided into at least two circumferentially adjacent fields that extend radially across the data tracks and include PES blocks that are DC magnetized in one direction, with each PES block having a magnetization opposite to the magnetization of its radially adjacent neighboring PES blocks. Each PES field is contiguous with and shifted radially relative to its circumferentially adjacent neighbor PES fields. Each PES block has a single DC magnetization, and the length of the magnetization is substantially longer than the length of the magnetizations in the other fields of the servo pattern.
    Type: Grant

  • Method, apparatus and article to load new instructions on processor based devices, for example, automatic data collection devices
    Patent number: 7761864
    Abstract: Methods, apparatus and articles facilitate the loading of a set of new instructions to replace set of existing instructions on a processor based device, for example an automatic data collection device. For example, a new operating system may replace an existing operating system using an executable that disables interrupts and/or exceptions. The new operating system may execute with, or without booting. The set of new instructions may be fragmented to fit the block size of a nonvolatile programmable memory, and/or may be compressed. Validation values such as check sums and/or error correction may be employed.
