Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
101 words
A TOC recording device (Fig. 5) comprises: starting terminal searching means (503) for searching the starting terminal on a first side of a tape having two recording side; first TOC recording means (504) for recording a first TOC at the starting terminal on the first side; record starting point searching means (505) for searching the starting terminal or record starting point on the second side; and second TOC recording means (506) for recording a second TOC having the same content as that of the first TOC at the starting terminal or record starting point on the second side of the tape.
Claim 2
Dependent Claim
189 words
A TOC recording/reproducing device (Fig. 9) comprising: tape position detecting means (902) for detecting a position on a tape to output tape position information; tape length detecting means (903) for detecting a tape length to output tape length information; first TOC searching means (905, 9l2) for searching, on the basis of said tape position information and said tape length information, a first TOC at either the starting terminal on the first side or the starting terminal or record starting point on the second side; TOC reproducing means (907, 9l3)) for reproducing said searched first TOC; TOC creating means (908, 9l4) for creating a new TOC data on the basis of said reproduced first TOC; first TOC recording means (909, 9l5) for recording a third TOC on said reproduced first TOC on the basis of said new TOC data; second TOC searching means (9l0, 9l6) for searching a second TOC on the side on which said third TOC is not still recorded; and second TOC recording means (9ll, 9l7) for recording again a fourth TOC having the same content as that of said third TOC on said searched second TOC.
Claim 3
Dependent Claim
92 words
A TOC reproducing device (Fig. 7) comprising: tape position detecting means (702) for detecting a position on a tape to output tape position information; tape length detecting means (703) for detecting a tape length to output tape length information; TOC searching means (705. 706) for searching, on the basis of said tape position information and said tape length information, either of TOCs at the starting terminal on the first side and the starting terminal or record starting point on the second side; and TOC reproducing means (707) for reproducing said searched TOC.
Claim 4
Dependent Claim
28 words
A TOC recording/reproducing device according to claim 2, wherein said tape length detecting means comprises identification code reading means for reading an identification code recorded on a cassette.
Claim 5
Dependent Claim
28 words
A TOC reproducing device according to claim 3, wherein said tape length detecting means comprises identification code reading means for reading an identification code recorded on a cassette.
Claim 6
Dependent Claim
28 words
A TOC recording/reproducing device according to claim 2, wherein said TOC searching means comprises terminal detecting means for detecting the starting terminal or ending terminal of the tape.
Claim 7
Dependent Claim
28 words
A TOC reproducing device according to claim 3, wherein said TOC searching means comprises terminal detecting means for detecting the starting terminal or ending terminal of the tape.
