Abstract: Data on a storage medium are refreshed by reading the data from a first location on the storage medium, storing them to a second location, and reading the data from the second location and storing them at the first location. The first and second locations are first and second physical locations and a logical address is initially associated with the first physical location. When the data are stored at the second location, the association of the logical address is changed to the second physical location. When the data are stored again at the first location, the association of the logical address is changed to the first physical address. The process is performed iteratively on the basis of successive logical block addresses. If the storing the data at the first location is interrupted, the data is re-read from the second location, and re-stored to the first location.

Abstract: Systems and methods are provided through which a minimized sector variable-bits-per-inch table (MSVBPI) is generated during the design of the mass storage device. The MSVBPI table maps variable-bits-per-inch parameters to a head and zone. The retrieval of parameters is accomplished entirely from the MSVBPI table. Furthermore, the MSVBPI table is stored on the recording medium of the mass storage device. The firmware of the mass storage device is stored in the read-only-memory of the mass storage device. During the design of the mass storage device, after an initial compilation of the firmware, the firmware does not need to be recompiled when the content of the MSVBPI table is changed because the content of the MSVBPI and the firmware do not affect the content of each other.

Abstract: Method and apparatus for detecting defects in a magnetic medium of a data handling system. The magnetic medium includes a number of user data wedges each disposed between an adjacent pair of servo data wedges. A predetermined data sequence is written to the user data wedges, and subsequently read to generate a readback signal. A sequence of discrete time sample values are generated from the readback signal. Defects in the medium are detected in relation to the magnitudes of the discrete time samples. A media scan controller outputs a first multi-bit information record having at least one bit composing the address of the user data wedge containing a defect, and a second multi-bit information record having at least one bit composing an address of the defect within the user data wedge. No information is written to the buffer when no defects are identified.
