Information recording/reproducing apparatus using an optical recording medium.

摘要

An information recording apparatus comprises a data converting means 10 for performing data conversion on record information consisting of a digital signal in accordance with a predetermined data conversion table, a data modulating means 6 for inverting an initial output signal when bit information of data after the data conversion is "1" given that the initial output signal is "0"; and a recording means 3 for recording the output signal on an optical recording medium. An information reproducing apparatus comprises a reading means 7 for reading information from the optical recording medium to yield a reproduced signal; a level detecting means 11 for detecting a level of the reproduced signal and outputting digital data; an error connecting correcting means 12 for, upon detection of a sequence of "01110" in a bit pattern of the digital data, correcting the sequence to a sequence of "01010" and outputting corrected data, and, upon detection of no error, outputting the digital data; and a data reverse converting means 13 for performing reverse conversion on the output data of the error correcting means in accordance with the data conversion table, yielding reproduced information. <IMAGE> <IMAGE>
