    摘要： A data storage device has multiple storage media surfaces and corresponding heads, each storage media surface includes multiple regions, and each head is for recording on and playback of information from a corresponding storage media surface. A method of defining a storage format for the storage media surfaces includes reading data from each region on each storage media surface with the corresponding head, measuring a record/playback performance of each head for each region on each corresponding storage media surface based on the data read from the regions, and selecting a track density for each region on each storage media surface based on the measured record/playback performance of the corresponding head for the region.

    摘要： A method for dynamic spiral ISR scheduling determines a dynamic delay with spiral to spiral spacing information of a disk, so as to ensure that the sum of a primary ISR time and a secondary ISR time does not exceed the wedge to wedge time. The ISR time may be scheduled to start after a delay for the sum of a static delay and the dynamic delay from an edge. A system for dynamic spiral ISR scheduling uses a dynamic delay determining unit to determine a dynamic delay, and an ISR scheduling unit to schedule the start of a secondary spiral set ISR based on a sum of the dynamic delay and a static delay.

    摘要： Digital control of actively mode-locked lasers where an active feedback control system is implemented to include a digital processor such as a microprocessor. The digital processor digitally extracts noise information from multiple monitor signals generated from the laser output and digitally diagnoses the operating condition of the laser based on the noise information. Based on the operating condition of the laser, the digital processor generates control signals to adjust the laser cavity to establish or regain the mode locking condition and to maintain the mode locking by reducing the output noise.

    摘要： Methods, systems and computer program products for detecting an end of a reference spiral band are described. A first portion of servo information may be written on a disk using the reference spiral band. By detecting an end of a reference spiral band, a new reference spiral band may be launched. A read/write head of a hard disk drive may subsequently use the new spiral band to write the remaining portion of the servo information, which aids the writing of data tracks on the disk.

    摘要： Methods, systems, and apparatus, including computer program products, are described for calibrating servos, and in some implementations for calibrating spiral servos for use in self servo write processes. In one aspect, a method is provided that includes measuring a slope of a spiral written to a machine readable medium, and adjusting a parameter in accordance with the measured slope to calibrate spacing of servo tracks, with respect to variation between a target slope and the measured slope for the spiral, for writing the servo tracks to the machine readable medium using the spiral as a reference and the adjusted parameter to generate a same radial spacing between servo tracks from spirals with different slopes.
