Abstract:
A reproducing device for reproducing data from a magneto-optical medium including a magnetic layer having different magnetic characteristics depending upon temperature, comprising:a peak detector for detecting a peak in a reproduced waveform in reproducing data from a magneto-optical recording area where said peak corresponds to one of ""1"" and ""0"" of the data;an edge detector for detecting an edge in a reproducing waveform in reproducing data from a pre-formatted recording area where said edge corresponds to one of ""1"" and ""0"" of the data at substantially the same linear recording density as in said magneto-optical recording area;a synchronous clock generator for generating a synchronous clock signal having substantially the same frequencies in reproducing the respective data in said magneto-optical recording area and said pre-formatted recording area; anda data discriminator commonly used to reproduce the data from said magneto-optical recording area and said pre-formatted recording area for discriminating the data on the basis of a respective output from said peak detector and said edge detector in response to the synchronous clock signal.
