摘要：A data recovery circuit for reading data stored in a plurality of ctors formed on a recording disk compris a clock recovery circuit (410) that generates a plurality of clock signals and produces an output formatted data stream by passing an input英文好句

clock signals reprent a recovered clock signal when the switch signal is asrted and reprent a reference clock signal when the switch signal is deasrted. A format control circuit (412) asrts the switch signal when a ctor pul signal is detected, detects the formatted data stream, reads the data stored in the identification field of a ctor and determines a current ctor number, asrts the switch signal at the beginning of the data field of a ctor and reads the data stored in the data field regardless of whether the current ctor number is equal to a arch ctor number, ignores the data stored in the data field when the current ctor number is unequal to the arch ctor number, generates a stream of unformatted data in respon to the data stored in the data field when the current ctor number is equal to the arch ctor number, and deasrts the switch signal for a predetermined time when an interrupt signal is asrted. A demarcation circuit (414) counts the plura手工简单又漂亮
