Document Type and Number:
Japanese Patent JPS4838110
Kind Code:
A
Abstract:
In a magnetic tape for recording a sound sequence in relation to an image sequence to be recorded on a film, a control signal sequence which corresponds to each constitutional part of said image sequence in a film is recorded. A tape recorder is used for recording sound information which is quite independent of said sound sequence, to effect after-recording of sound which corresponds to the image on the film. Other control signals entirely different from said control signal sequence, for moving the film and a tape synchronously, are recorded through the tape recorder simultaneously with the after-recording. In such manner, a sound signal formed by simultaneous recording with a camera and a sound signal formed by after-recording on one roll of a film are selectively and synchronously reproduced.
