Title: Optical disk recording device
Inventor: SAKUMA HIROTO
IPC: G11B27/10
Filed: 1992-06-23
Abstract: PURPOSE:To reproduce a recorded track of an optical disk on the way of recording by a player dedicated to reproduction by recording index information in the index area and recognizing the index information. CONSTITUTION:Time information for tracks which are not yet recorded, but assigned at equal intervals and a maximum recordable track number at this time are recorded in a data recording area 23 simultaneously with the end of recording of the index information. Thus, the recording in the index information area 20 and divisional time recording for the remaining user recordable area 24 is ended and then this disk can be reproduced by a player dedicated to reproduction even still in a additional recordable state since the index information is recorded. Then the respective track areas in the additional recordable state are divided at equal intervals, so the need to recognize the start time codes of the tracks divided at the equal intervals is eliminated only by reproducing and recognizing the assigned time of the respective tracks which are recorded and the maximum track number indicating to what extent the recording is possible without recognizing the start time codes of the respective tracks in the additional recordable area.
