Optical disk mastering apparatus having two data transferring rates for recording and monitoring |
摘要 |
A disk recording and reproducing apparatus which realizes a simultaneous monitoring function with a recording function with a simple pickup system is disclosed. The apparatus comprises a recording and reproducing head, a first memory for receiving and storing input signals at a first rate and supplying the stored signals at a second rate higher than the first rate so as to be recorded onto the disk medium at the second rate by means of the recording and reproducing head, a second memory for receiving and storing signals reproduced at the second rate by means of the recording and reproducing head and outputting the stored signals at a rate lower than the second rate, and a controller for controlling the recording and reproducing head to relatively scan a same portion of the disk medium twice for a predetermined period of time so that recording and reproduction occur alternately and successively at the portion of the disk medium for each predetermined number of blocks.
