Systems and methods for optimizing optical recording

摘要

Systems and methods are provided for reducing jitter in a write strategy for an optical drive. A pattern on an optical medium is recorded according to a first write strategy. Edge timings corresponding to the pattern recorded on the optical medium are measured, and edge timing sensitivities are determined based at least in part on the measured edge timings. A second write strategy is determined based on the edge timing sensitivities, such that the second write strategy is associated with a second jitter amount less than a first jitter amount associated with the first write strategy.

1. A method for reducing jitter in a write strategy for an optical drive, comprising:
recording a pattern on an optical medium according to a first write strategy; measuring edge timings corresponding to the pattern recorded on the optical medium; determining edge timing sensitivities based at least in part on the measured edge timings; calculating at least one derivative of an error function based on the edge timing sensitivities; and determining a second write strategy based on the at least one derivative of the error function, such that the second write strategy is associated with a second jitter amount less than a first jitter amount associated with the first write strategy.
