1. An optical disk recording and reproducing method comprising the steps of:

  • receiving an operator'"'"'s signal to record a data on a multi-layered optical disk at indicated data compression rate;

    accessing to a read-in region to record the data;

    operating a routing circuit to transmit the data to data compressing means which compresses the data at the indicated data compression rate;

    recording the data at the indicated data compression rate, and on the indicated region;

    rewriting a total of contents (TOC) data to record data about the data compression rate of the newly recorded data;

    reproducing the TOC data recorded in the multi-layered optical disk;

    storing the reproduced TOC data in a memory;

    receiving the operator'"'"'s signal to reproduce the data recorded in the multi-layered optical disk;

    referring the TOC data stored in the memory to identify the data compression rate of the data; and

    operating a routing circuit to transmit readout signal of the data to data decompressing means which decompresses the data from the indicated data compression rate to a standardized bit rate of data signal.
