Patent ID: 7149166

Claim:
An optical recording system for burning an optical disc, the optical recording system comprising: a housing; a laser pickup installed inside the housing for writing data onto the optical disc according to a write strategy and reading an RF signal from the optical disc; a laser drive installed inside the housing connected to the laser pickup for controlling operations of the laser pickup; a read channel installed inside the housing connected to the laser pickup for processing the RF signal received by the laser pickup; a jitter meter installed inside the housing connected to the read channel for generating delay signals according to the processed RF signal; and a digital signal processor installed inside the housing connected to the laser drive and the jitter meter for receiving the delay signals, configuring the write strategy according to the delay signals, and controlling the laser drive to control the laser pickup to write data onto the optical disc according to the configured write strategy; wherein the jitter meter includes: a delay chain having a plurality of delay cells connected in a cascade manner, each delay cell delaying an input signal a time unit; a buffer set connected to the delay chain for storing a delay signal received from the delay chain, the buffer set having a plurality of buffers each connected to a delay cell for receiving a delay bit of the delay signal transmitted from the delay cell; and a control unit connected to the read channel and the buffer set for outputting a control signal according to a standard clock and the processed RF signal.
