Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
154 words
A recording and reproducing apparatus comprising: a) main recording and reproducing means for recording and reproducing a main signal on and from a recording medium; b) auxiliary recording and reproducing means for recording and reproducing, on and from said recording medium, table-of-contents information which is to be used in making a search for said main signal; c) erasing means for erasing said table-of-contents information recorded on said recording medium; d) a memory for storing said table-of-contents information; e) loading detecting means for detecting that the apparatus is loaded with said recording medium; and f) control means arranged to cause said auxiliary recording and reproducing means to reproduce said table-of-contents information according to an output of said loading detecting means, to cause said reproduced table-of-contents information to be written in said memory and to cause said erasing means to erase, from said recording medium, said table-of-contents information reproduced by said auxiliary recording and reproducing means.
Claim 2
Dependent Claim
154 words
A recording and reproducing apparatus comprising: a) main recording and reproducing means for recording and reproducing a main signal on and from a recording medium; b) auxiliary recording and reproducing means for recording and reproducing, on and from said recording medium, table-of-contents information which is to be used in making a search for said main signal; c) erasing means for erasing said table-of-contents information recorded on said recording medium; d) a memory for storing said table-of-contents information; e) loading detecting means for detecting that the apparatus is loaded with said recording medium; and f) control means arranged to cause said auxiliary recording and reproducing means to reproduce said table-of-contents information according to an output of said loading detecting means, to cause said reproduced table-of-contents information to be written in said memory and to cause said erasing means to erase, from said recording medium, said table-of-contents information reproduced by said auxiliary recording and reproducing means.
Claim 3
Dependent Claim
33 words

Claim 4
Dependent Claim
52 words
An apparatus according to claim 2, wherein said control means is arranged to cause said transport means to rewind said tape-shaped recording medium by a predetermined amount according to an output of said loading detecting means and, after that, to cause said auxiliary recording and reproducing means to reproduce said table-of-contents information.
Claim 5
Dependent Claim
73 words
An apparatus according to claim 1, further comprising eject instructing means which gives an instruction for ejecting said recording medium from the apparatus, and wherein said control means is arranged to read out said table-of-contents information stored in said memory in response to an output of said eject instructing means and to cause said auxiliary recording and reproducing means to record on said recording medium said table-of-contents information read out from said memory.
Claim 6
Dependent Claim
38 words
An apparatus according to claim 4, further comprising ejecting means for ejecting said recording medium in response to the instruction of said eject instructing means after said table-of-contents information is recorded by said auxiliary recording and reproducing means.
Claim 7
Dependent Claim
32 words
An apparatus according to claim 4, wherein said recording medium is a tape-shaped recording medium, said apparatus further comprising transport means for transporting said tape-shaped recording medium in the longitudinal direction thereof.
Claim 8
Dependent Claim
52 words
An apparatus according to claim 6, wherein said control means is arranged to cause said transport means to rewind said tape-shaped recording medium by a predetermined amount according to an output of said loading detecting means and, after that, to cause said auxiliary recording and reproducing means to record said table-of-contents information.
Claim 9
Dependent Claim
33 words
An apparatus according to claim 1, further comprising rewriting means for rewriting said table-of-contents information recorded in said memory according to the main signal recording action of said main recording and reproducing means.
