Abstract

PURPOSE: To easily judge where an user is now reproducing even in a high speed reproducing state by writing the digital data obtd. in the high speed reproducing state of a disk in a memory in a certain quantity and reading at a standard reproducing speed.
CONSTITUTION: The double speed digital data output from a 2nd digital signal processing circuit 13 are written in a memory 17 simultaneously with the double speed reproduction of a disk being started at a time T1. The writing operation to the memory 17 is stopped at the time T2 when the digital data of a certain quantity are written in the memory 17 and the digital data are read on a D/A converting circuit 18 at the standard speed from the memory 17 instead. It is written again to the memory 17 at the time T3 when all of the digital data are read and read at the standard speed at the time T4 when the digital data of a certain quantity are written on the memory 17. The reproduction contents can thus be easily recognized even in a double speed reproducing state and where an user is now reproducing can be easily judged.
