Abstract: Methods relating to compensating a pre-defined seek profile for use in a data storage device, such as a disc drive, to manage the internal temperature of the device are disclosed. One embodiment disclosed is related to determining a seek profile compensation value that can be used to compensate the pre-defined seek profile for temperature. Another embodiment is a method of using a seek profile compensation value during device operation to maintain the data storage device operating temperature below an operating temperature threshold. Yet another embodiment of the present invention may be thought of as a controller for a data storage device. The controller comprises a microprocessor having a pre-determined seek profile and a means for compensating the pre-determined seek profile based on a current operating temperature.

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: An apparatus and method for writing a product information code (PIC) to a head-disc assembly (HDA) of a disc drive data handling system to facilitate subsequent identification of the HDA. The PIC is configured as a sequence of n multi-bit encoded words. Servo data are written to a disc of the HDA as a number of p angularly spaced apart servo data fields, the servo data used by a servo control circuit to effect head positional control. The n encoded words are distributed across a subset n of the p servo data fields so that the n encoded words replace at least a portion of the servo data in the n servo data fields. Preferably, the n encoded words are written to Gray code (track address) fields of the n servo data fields and are provided with error detection and correction capabilities.
