Abstract

Disclosed is an information signal recording and reproducing apparatus which comprises first recording means for recording an information signal on a recording medium; first reproducing means for reproducing the information signal from the recording medium; second recording means for recording a control signal on the recording medium (the control signal corresponding to an optional quantity of the information signal); second reproducing means for reproducing the control signal from the recording medium; and control means for controlling the reproducing action of said first reproducing means in response to the control signal reproduced by said second reproducing means.

Claims

1. A video tape recorder, comprising:

(a) first recording means including at least one rotary head for recording a video signal on a first area of a magnetic tape;

(b) first reproducing means including at least one rotating head for reproducing the video signal from the first area of the magnetic tape;

(c) moving means for moving the magnetic tape in its lengthwise direction;

(d) manually operable means for designating a mode of the video tape recorder among a plurality of modes, said plurality of modes including a recording mode, a normal reproduction mode, a searching reproduction mode, and a quick feeding mode;

(e) second recording means including at least one fixed head for recording a mark signal on the second area of the magnetic tape, said fixed head recording said mark signal on the second area of the tape for a specific period in response to a specific manual operation for designating the recording mode of said manually operable means;

(f) second reproducing means for reproducing the mark signal from the second area of the tape;

(g) mode cotnrol means for changing over the video tape recorder among said plurality of modes in response to manual operations of said manually operable means and said mark signal reproduced by said reproducing means,

said mode control means being arranged to be able to bring the recorder into the searching reproduction mode only for a predetermined period in response to the reproduction of the mark signal being started by said second reproducing means and to maintain the recorder in the quick feeding mode for periods other than said predetermined period;

wherein when the recorder is in the recording mode, said first recording means records the video signal and said moving means moves the tape at a first speed,

when the recorder is in the reproducing mode, said first reproducing means reproduces the video signal and said moving means moves the tape at said first speed;

when the recorder is in the searching reproduction mode, said first reproducing means reproduces the video signal and said moving means moves the tape at a second speed faster than said first speed, and when the recorder is in the quick feeding mode, said first reproducing means does not reproduce the video signal and said moving means moves the tape at a third speed faster than said first speed.

2. A recorder according to claim 1, wherein:

said plurality of modes further includes a slow motion reproduction;

wherein when the recorder is in the slow motion reproduction mode, said first reproducing means reproduces the video signal and said moving means moves the tape at a fourth speed slower than said first speed.

3. A recorder according to claim 2, wherein:

said mode control means is arranged to be able to bring the recorder into the slow motion reproduction mode only for a predetermined period in response to the reproduction of the mark signal being started by said second reproducing means and to maintain the recorder in the quick feeding mode for periods other than said predetermined period.
