    摘要： Two recording tracks (Tl) and (T2) are formed in parallel on a three-dimensional video disc record (D). Video data for the right eye and voice data are continuously recorded on one recording track (T1). On the other recording track (T2) are continuously recorded video data for the left eye and voice data in synchronism with the video data for the right eye and voice data that are recorded on the neighboring recording track (T1). Video data for the right eye, video data for the left eye and voice data can be recorded easily and simultaneously onto the three-dimensioned video disc record (D) using two recording beams. The three-dimensional video data can be reproduced by simultaneously reproducing these two recording tracks using two reproducing beams. The ordinary plain video data can also be reproduced by continuously reproducing either one of the recording tracks using a single reproducing beam.

    摘要： An magneto-optical disc recording/reproducing apparatus includes an optical head (36) to detect a wobble (46) and an address mark (81 to 84) in an magneto-optical disc (31) and output a wobble signal (WB1, WB2) and an address mark signal (AML, AMG), a PLL circuit (47) to generate a clock signal (CK) in response to wobble signal (WB1), an address mark synchronous signal generation circuit (46) to generate an address mark synchronous signal (AM) in response to address mark signal (AML, AMG), a synchronizing circuit (48) to synchronize clock signal (CK) with address mark synchronous signal (AM) and generate a synchronized clock signal (SCK), and a timing setting circuit (49) to generate a timing pulse signal (TG1) to control a magnetic head driving circuit (34) and a timing pulse signal (TG2) to control a laser driving circuit (35). The recording/reproducing apparatus can detect a address mark (81 to 84), record a data signal on magneto-optical disc (31) in synchronization with the detected address mark, and reproduce a data signal from magneto-optical disc (31) in synchronization with the detected address mark, so that the data signal can be surely recorded/reproduced.
