ABSTRACT:
A disc recording and reproducing apparatus for using an optical disc having a recording area in which information signals are recorded and a lead-in area in which data related to the information signals recorded in the recording area is recorded includes a timer, a display, recording and reproducing apparatus and a controller. The timer counts at least the current time and outputs time data. The display displays time corresponding to the time data. The recording and reproducing apparatus records and reproduces the information signals and the time data on the optical disc. The controller controls the recording and reproducing apparatus and the display. The recording and reproducing apparatus is controlled by the controller during the recording for recording the information signals in the recording area of the optical disc and for recording the time data from the timer in the lead-in area of the optical disc. The recording and reproducing apparatus is also controlled by the controller during the playback for reading and reproducing the information signals recorded in the recording area. The display is controlled by said controller to display the time corresponding to the reproduced time data.
