摘要： A disk recording and reproducing device records and reproduces information on and from a magneto-optical disk having absolute addresses and including an information recording area wherein pieces of information entered from external devices are recorded and a TOC area wherein additional information with respect to each piece of the information recorded in the information recording area is recorded. The device includes operation keys for being operated by the user, a TOC memory for storing therein read/write control information for desired pieces of information entered through the operation keys, an optical head and a magnetic coil for recording in the TOC area the contents stored in the TOC memory as additional information and a controller for controlling read/write operation to the disk according to the read/write control information. With the arrangement, the user can recognize necessary/unnecessary information and defective parts in the disk, and therefore make effective use thereof as well as maintaining secrecy of the information. A disk recording and reproducing device also includes a peak level detection circuit for detecting peak levels of music information, a TOC memory for storing therein peak level information with respect to the peak levels, and an optical head and a magnetic coil for recording in the TOC area the contents stored in the TOC memory as additional information, thereby permitting the user to readily perform preferable copying operation. A disk recording and reproducing device further comprises an optical head and a magnetic coil whereby an end mark is recorded in the rear end part of the additional information, and when a new piece of information is recorded in the information recording area, additional information with respect to the new piece of information is overwritten to add onto an end mark already recorded in the TOC area, and an end mark is newly recorded in a rear end part of the overwritten additional information. Thus, required reproducing time for the TOC area can be shortened. A disk recording and reproducing device includes an optical head for applying a light beam to the disk in recording information, operation keys, memory means wherein an absolute address corresponding to the time when the operation key is operated to initiate recording is stored, and optical head drive control means for moving the optical head back to a vicinity of a position indicated by the absolute address stored in the memory means and for keeping the optical head in a stand-by state by making it perform track-jumps at a position slightly before the position indicated by the absolute address, when re-recording operation of information is performed. Therefore, in re-recording information, the optical head is readily accessed to a vicinity of a recording start position of the former information.

摘要： A data recording and reproducing apparatus uses a rewriteable optical disk (1) with pre-recorded absolute address information, and comprises a data compression circuit (23, 20) for dividing and compressing continuous digital data into compressed plural data blocks, an expansion circuit (21, 28) to restore the compressed data to the original expanded form, and a buffer memory (19). Data is compressed in discrete data blocks and is recorded sequentially block by block to the optical disk. The compressed data is likewise read block by block from the disk during data reproduction. Using the data expansion circuit to expand the compressed data one block at a time, the data recording and reproducing apparatus can reproduce the original continuous digital data stream. Plural continuous digital data selections can thus be reproduced by alternately fetching data for the plural selections from the disk in compressed data block units and temporarily storing the data to a buffer memory for expansion.
