Abstract
1,116,075. Recording and playback apparatus. SONY CORPORATION. 16 Nov., 1965 [16 Nov., 1964], No. 48579/65. Heading G5R. A recording and playback system of the type described in Specification 1,116,074 is modified by the inclusion of two pulse generators which provide synchronizing signals for combining with played back video signals during the playback of normal motion picture signals and still picture signals respectively. For playing back motion signals, the heads scan at the same angle as the recorded tracks, and the synchronizing pulse generator comprises magnets 15a, 15b spaced 360 degrees/n around a disc 14 which rotates with the head assembly and a pickup coil 16. The pulses produced from the coil 16 are shaped and mixed with the played-back video signal at 19. For playing back still pictures, the tape remains stationary, and the heads accordingly scan at a different angle from recording. The synchronizing pulse generator comprises a similar disc 14<SP>1</SP> with magnets 15a<SP>1</SP>, 15b<SP>1</SP> the spacing between magnets differing from 360 degrees/n to compensate for the different scanning angle.
