Recording and/or reproducing method for an optical disc

摘要

A recording and/or reproducing method for using an optical disc (1) comprises recording or reproduction data on or from the optical disc (1) in predetermined data-length units. In a recording operation, the recording and/or reproducing method includes the step of dividing data read from the optical disc (1) in the predetermined sector length, rewriting inputted data into the desired sector which is divided from the predetermined data-length inputs and recording the data including the rewritten sector on the optical disc (1) in the predetermined data-length units. In a reproducing operation, the recording and/or reproducing method includes the step of reading the data from the optical disc (1) having the predetermined data-length units, dividing the data read from the optical disc (1) in the predetermined data-length units into the predetermined sector length and transferring data of the reproduced desired sector as output data.
