    摘要： In one embodiment, a magnetic disk drive includes a magnetic disk having data tracks, a magnetic head, a motion mechanism for moving the magnetic head, and a controller. The controller adds a value to a rewrite parameter for a rewrite region based on a number of writes to data tracks related to the rewrite region, the value is chosen to reflect a degree of influence the number of writes have on the rewrite region, and the magnetic head rewrites data of the rewrite region when the rewrite parameter is greater than a threshold. In another embodiment, a method includes writing data tracks in a rewrite region, defining values reflecting a degree(s) of influence on the rewrite region, adding the values to a rewrite parameter upon writing data to the data tracks, determining that the rewrite parameter has reached or exceeded a threshold and rewriting data in the rewrite region.

    摘要： A recording drive waveform adjusting method for manufacturing a master disc is provided. The method includes forming an exposed area in an inorganic resist layer for test exposure by irradiating a master disc having the inorganic resist layer with laser light of a recording power based on a recording drive waveform according to a test recording signal. The method also includes obtaining reflected-light information by irradiating the exposed area formed in the test exposure with laser light of a reproducing power, determining whether the recording drive waveform is appropriate by using the reflected-light information, and correcting the recording drive waveform if the recording drive waveform is determined to be inappropriate in the determination.

    摘要： Embodiments in accordance with the present invention help a disk drive to effectively cope with a data address mark detection error. In one embodiment, a data sector is provided with plural data address marks and an read/write (RW) channel reads out the data sector using part of those data address marks. Each divisional section of a split sector has two data address marks and the RW channel uses one of the two data address marks. A data address mark to be used is specified by a register. When an error occurs in detecting a data address mark, its position is stored in a register. Based on the error position, an error recovery processing section stores, in the register, a data address mark to be used in a next retry.

    摘要： A method of changing a program for controlling a disk drive that includes an EEPROM. The method includes storing a program block to a disk area such that the program block is associated with a second area for storing the program block that is not utilized for a read operation from the disk area. The method also includes storing a program block that is associated with a first area to an area that includes at least a portion of the second area in the EEPROM such that the first area contained a program block that is utilized for a read operation from the disk area. In addition, the method includes changing the program block in the first area after storing to the second area. Moreover, the method includes storing to the second area the program block that is not utilized for a read operation from the disk area after storing to the first area.
