摘要： A two-side video disc is manufactured by laminating a top side face disc having a HDTV video signal with red color signal component recorded and a back side face disc having a HDTV video signal with blue color signal component recorded at a position corresponding to the recorded signal on the top side face. Visual end marks are formed at the respective ends of recording tracks of the top side face and back side face discs. The two discs are laminated so that the positions of the end marks coincide with each other. This minimizes deviation in timings between the reproduced signals from the two sides of the disc to reduce significantly the memory capacity of a delay circuit.

摘要： A disk apparatus (10) includes an optical pick-up (12) and a DSP (28), and irradiates a laser beam onto a recording surface of a disk recording medium (100) by the optical pick-up. In a case that a time period (access time period) required for a seek is shorter than a time period (changing time period) required for the number of rotations, the DSP does not simultaneously perform a change of the number of rotations and the seek. To the contrary, the DSP delays the seek by |access time period−changing time period|, and performs a recording and a reproduction after the change of the number of rotation is ended.

摘要： A disc apparatus (10) includes an optical lens (14). A laser beam is irradiated onto a recording surface of the magneto-optical disc (68) through the optical lens (14), and a TE signal or an RF signal is detected on the basis of the laser beam reflected by the recording surface. Herein, an MPU (50) replaces the optical lens (14) in an optical axis direction, and a TE signal detection circuit (42) or an RF signal detection circuit (60) detects the TE signal or the RF signal at each of lens positions. A laser power is adjusted by the MPU (50) such that amplitude of each of the TE signal or the RF signal detected is below a saturation value. When a parameter is adjusted, a position of the optical lens (14) is controlled such that the amplitude of the TE signal or the RF signal detected thereafter is maximized.

The trick playback areas are enlarged to provide increment areas TA with a decrease in the bit rate of usual playback data.

In this method, a number of tracks in accordance with the number of speed multiplication for trick playback provide one TP frame, the same trick playback data is repeatedly recorded from track to track in the trick playback data areas of the tracks within the same TP frame, and the image data as to the programs A to D is cyclically recorded in such respective TP frames, each for one program.

摘要： A disk apparatus (10) includes a spindle (62) to which a magnetooptical disk (60) is attached. An FCM is formed on the magnetooptical disk (60) along a track at intervals of a predetermined period, a laser beam having a different light amount depending on a time of an execution and an interruption of a recording process is incident upon the track. The FCM signal detection circuit (36) detects an FCM signal based on the laser beam reflected from the track, a comparator (42) compares a level of the FCM signal and a slice level, and a PLL circuit (54) generates a clock signal based on a comparison result by the comparator (42). When a change request between an execution/interruption of the recording process is applied, a predetermined first slice level is set to the comparator (42) until 200 mili seconds passes since a reception of the change request. When 200 mili seconds passes, a second slice level calculated based on a peak level of the FCM signal is set to the comparator (42).
