Abstract
Abstract A multi-channel recording apparatus which is capable of recording one and the same main information by forming many parallel tracks in each of an m number of areas (m: an integer which is at least 1) among an n number of areas (n: an integer which is greater than m and is at least 2) longitudinally extending on a tape-shaped recording medium is arranged to record, in each of the m number of areas along with data relative to the main information, data indicative of that the data relative to the main information is recorded in and over a plurality of areas among the above stated areas when said number m is at least two.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
153 words
A recording apparatus comprising: (a) recording means for recording signals by forming many parallel tracks in an n number (n: an integer which is at least 2) of recording areas longitudinally extending on a tape-shaped recording medium; (b) input means for receiving main information; (c) recording signal forming means for forming, from said main information, recording signals in an m number of channels (m: an integer which is at least 1 but is less than n); (d) adding means for adding, to each of said recording signals of said m channels, sub-information including a first data which indicates whether the number m is 1 or more than 2; and (e) means for supplying said recording means with said recording signals of the m number of channels so that the recording signals of said m channels are recorded by said recording means in an m number of areas among said n number of areas.
Claim 2
Dependent Claim
153 words
A recording apparatus comprising: (a) recording means for recording signals by forming many parallel tracks in an n number (n: an integer which is at least 2) of recording areas longitudinally extending on a tape-shaped recording medium; (b) input means for receiving main information; (c) recording signal forming means for forming, from said main information, recording signals in an m number of channels (m: an integer which is at least 1 but is less than n); (d) adding means for adding, to each of said recording signals of said m channels, sub-information including a first data which indicates whether the number m is 1 or more than 2; and (e) means for supplying said recording means with said recording signals of the m number of channels so that the recording signals of said m channels are recorded by said recording means in an m number of areas among said n number of areas.
Claim 3
Dependent Claim
34 words
An apparatus according to claim 1, wherein said sub-information further includes second data indicating all of said m number of areas in which said recording signals of the m number of channels are recorded.
Claim 4
Dependent Claim
46 words
An apparatus according to claim 1, wherein said recording means includes a rotary head which is arranged to transversely trace said n number of areas; and said recording signals of the m number of channels are recorded by said rotary head in a time sharing manner.
Claim 5
Dependent Claim
14 words
An apparatus according to claim 1, wherein said main information includes a video signal.
Claim 6
Dependent Claim
24 words
An apparatus according to claim 4, wherein said recording signal forming means includes means for extracting one picture plane portion of said video signal.
Claim 7
Dependent Claim
161 words
A recording apparatus comprising: (a) recording means for recording signals by forming many parallel tracks in an n number (n: an integer which is at least 2) of recording areas longitudinally extending on a tape-shaped recording medium; (b) input means for receiving main information; (c) recording signal forming means for forming, from said main information, recording signals in an m number of channels (m: an integer which is at least 1 but is less than n); (d) adding means for adding, to each of said recording signals of said m channels, sub-information including a subordinate data which indicates, all of m number of areas where said recording signals of the m number of channels are recorded; and (e) means for supplying said recording means with said recording signals of the m number of channels so that the recording signals of said m channels are recorded by said recording means in said m number of areas among said n number of areas.
Claim 8
Dependent Claim
161 words
