Abstract
An apparatus for reproducing address data recorded on a disk record medium with an information signal which is recorded on the same by forming pit portions in response to the information signal included a pickup for optically reproducing the recorded data and signals is provided. Also the apparatus includes a circuit for generating a sampling pulse from the recorded data and signals so that the sampling pulse occurs substantially beginning position of a mirror portion beginning the pit portions, a circuit for sampling and holding the recorded data and signals by the sampling pulse, and a circuit for decoding an output signal of the sampling and holding means so as to generate the address data.
Claims3
An apparatus for reproducing address data recorded on a disk record medium with an information signal which is recorded on the same by forming pit portions in response to the information signal comprising:
- means for optically reproducing said recorded data and signals;
- means for generating a sampling pulse from said recorded data and signals so that said sampling pulse occurs at a substantially beginning position of a mirror portion between said pit portions;
- means for sampling and holding said recorded data and signals by said sampling pulse;
- and
- means for decoding an output signal of said sampling and holding means so as to generate said address data.
