Abstract

Abstract An apparatus for recording an analog video signal in a longitudinally extending first area of a tape-shaped recording medium and for recording a digital audio signal in a second area of the medium extending in parallel to the first area is arranged: to bring the video and audio signal recording to a stop; to record control data in the second area along with the audio signal immediately before the stop; and to start to record the digital video signal and the analog audio signal when the control data is reproduced from the second area.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 157 words
A video signal recording apparatus comprising: (a) recording means for recording an analog video signal by obliquely forming recording tracks on a tape shaped recording medium within a first area which extends in the longitudinal direction of the medium and for recording a digital audio signal by obliquely forming recording tracks in a second area which extends in parallel to said first area; (b) first control means for generating an instruction signal for causing said recording means to stop recording said video and audio signals; (c) second control means for causing, in response to said instruction signal, said recording means to record, in said second area, control data indicative of a stop made in recording; (d) reproducing means for reproducing said control data from said second area; and (e) third control means for causing said recording means to start recording said video and audio signals on the basis of said control data reproduced by said reproducing means.
Claim 2
Dependent Claim 157 words
A video signal recording apparatus comprising: (a) recording means for recording an analog video signal by obliquely forming recording tracks on a tape shaped recording medium within a first area which extends in the longitudinal direction of the medium and for recording a digital audio signal by obliquely forming recording tracks in a second area which extends in parallel to said first area; (b) first control means for generating an instruction signal for causing said recording means to stop recording said video and audio signals; (c) second control means for causing, in response to said instruction signal, said recording means to record, in said second area, control data indicative of a stop made in recording; (d) reproducing means for reproducing said control data from said second area; and (e) third control means for causing said recording means to start recording said video and audio signals on the basis of said control data reproduced by said reproducing means.
Claim 3
Dependent Claim 52 words
An apparatus according to claim 1, wherein said recording means includes a rotary head which is arranged to transversely trace the surface of said recording medium across said first and second areas and to be capable of recording said control data along with said analog video signal and said digital audio signal.
Claim 4
Dependent Claim 21 words
An apparatus according to claim 1, further comprising moving means for moving said tape-shaped recording medium in the longitudinal direction thereof.
Claim 5
Dependent Claim 51 words
An apparatus according to claim 3, wherein said second control means is arranged to cause said recording means to make a stop in recording said video and audio signals after causing said recording means to record said control data for a given period of time in response to said instruction signal.
Claim 6
Dependent Claim 41 words
An apparatus according to claim 4, wherein said second control means is arranged to cause said moving means to reverse the recording medium moving direction after causing said recording means to make a stop in recording said video and audio signals.
Claim 7
Dependent Claim 55 words
An apparatus according to claim 5, wherein said second control means is arranged to cause said moving means to bring the recording medium moving action thereof to a stop after the lapse of a given period of time from a point of time when the recording medium moving direction of the moving means is reversed.
Claim 8
Dependent Claim 56 words
An apparatus according to claim 3, further comprising instruction means arranged to generate an instruction signal for instructing said recording means to start to record said video and audio signals; and wherein said third control means is arranged to cause, in response to said instruction signal, said moving means to start to move said recording medium.
Claim 9
Dependent Claim 26 words
An apparatus according to claim 7, wherein said instruction means is arranged to be capable of producing said instruction signal in response to a manual operation.
Claim 10
Dependent Claim 24 words
An apparatus according to claim 3, wherein said first control means is arranged to generate said instruction signal in response to a manual operation.
Claim 11
Dependent Claim 31 words
An apparatus according to claim 3, further comprising means for generating pilot signals for tracking control and for causing said recording means to record said pilot signals o said recording medium.
Claim 12
Dependent Claim 32 words
An apparatus according to claim 10, further comprising tracking control means for controlling the recording medium moving action of said moving means on the basis of signals reproduced by said reproducing means.
Claim 13
Dependent Claim 236 words
A control method for a video signal recording apparatus, comprising: (a) a step of longitudinally moving a tape-shaped recording medium, recording an analog video signal on said medium by obliquely forming recording tracks on said medium within a first area extending in the longitudinal direction of said medium and recording a digital audio signal also on said medium by obliquely forming tracks in a second area extending in parallel to said first area; (b) a step of giving an instruction for making a stop in the recording actions of said step (a); (c) a step of recording, in said second area, control data indicative of said recording stop int he response to said instruction for making a stop in recording; (d) a step of bringing said recording to a stop after said control data is recorded; (e) a step of reversing the recording medium moving direction after said recording comes to have a stop; (f) a step of bringing a recording medium moving action to a stop when a given period time lapses after the medium moving direction is reversed; (g) a step of giving an instruction for a start of said recording; (h) a step of begining to move said recording medium in response to said instruction for a start of recording; and (i) a step of starting said recording when said control data is reproduced after the start of movement of said recording medium.
Claim 14
Dependent Claim 236 words
A control method for a video signal recording apparatus, comprising: (a) a step of longitudinally moving a tape-shaped recording medium, recording an analog video signal on said medium by obliquely forming recording tracks on said medium within a first area extending in the longitudinal direction of said medium and recording a digital audio signal also on said medium by obliquely forming tracks in a second area extending in parallel to said first area; (b) a step of giving an instruction for making a stop in the recording actions of said step (a); (c) a step of recording, in said second area, control data indicative of said recording stop int he response to said instruction for making a stop in recording; (d) a step of bringing said recording to a stop after said control data is recorded; (e) a step of reversing the recording medium moving direction after said recording comes to have a stop; (f) a step of bringing a recording medium moving action to a stop when a given period time lapses after the medium moving direction is reversed; (g) a step of giving an instruction for a start of said recording; (h) a step of begining to move said recording medium in response to said instruction for a start of recording; and (i) a step of starting said recording when said control data is reproduced after the start of movement of said recording medium.
