Reproducing apparatus for record disc

A reproducing apparatus comprising

• (i) a reading device for reading reproduction data and reproduction control data to control a reproduction of the reproduction data from a record disc, on which the reproduction data and the reproduction control data are recorded,
• (ii) a record medium having a plurality of memory areas,
• (iii) a data managing device for storing one reproduction control data read by said reading device into one of the memory areas, and
• (iv) a reproducing device for reproducing the reproduction data in accordance with the reproduction control data stored in the memory areas,
• said data managing device comprising:
• a retention priority memory for storing retention priority data, which indicate a retention priority as for each reproduction control data respectively stored in the memory areas;
• a usage frequency memory for storing usage frequency data, which indicate the number of times of usage as for each reproduction control data respectively stored in the memory areas;
• a selecting device for selecting one of the memory areas, into which the one reproduction control data read by said reading device is to be stored, on the basis of the retention priority data stored in said retention priority memory and the usage frequency data stored in said usage frequency memory, when the one reproduction control data is read by said reading device;
• and
• a storing device for storing the one reproduced control data read by said reading device into the memory area selected by said selecting device.
