Abstract:
A disc reproducing apparatus in which a data signal recorded on a disc is optically read out from said disc and reproduced as a data signal, comprising:pickup means for tracing a track formed on said disc to optically read out the signal recorded on said disc;first decoding means for decoding an output signal of said pickup means and then outputting digital data at a first transfer rate;memory means in which digital data output from said first decoding means is stored temporarily;control means for controlling write and read of said memory means such that said digital data output from said first decoding means is intermittently written in said memory means at said first transfer rate and said digital data written in said memory means is continuously read out from said memory means at a second transfer rate lower than said first transfer rate;second decoding means for decoding said digital data read out from said memory means and outputting data signal at said second transfer rate;calculating means for calculating an amount of digital data stored in said memory means; anddisplay means for providing a graphic representation of an amount of said digital data stored in said memory means as calculated by the calculating means to thereby permit a visual confirmation of a change in of said amount.
