Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
159 words
An optical disc recording apparatus for recording a desired information signal in a recording area of an optical disc in which table of contents data based on the information signal recorded in the recording area is recorded on one portion of the recording area, the apparatus comprising: writing means for writing said information signal in a recording area and for writing said table of contents data in a temporary area outside of said one portion of the recording area; reading means for reading out said table of contents data from said temporary area; and control means for controlling said writing means to write a further desired information signal in a predetermined area outside of said recording area responsive to reading out said table of contents from said temporary area and for controlling said writing means to write in said one portion of the recording area new data based upon said further desired information signal recorded in said predetermined area.
Claim 2
Dependent Claim
159 words
An optical disc recording apparatus for recording a desired information signal in a recording area of an optical disc in which table of contents data based on the information signal recorded in the recording area is recorded on one portion of the recording area, the apparatus comprising: writing means for writing said information signal in a recording area and for writing said table of contents data in a temporary area outside of said one portion of the recording area; reading means for reading out said table of contents data from said temporary area; and control means for controlling said writing means to write a further desired information signal in a predetermined area outside of said recording area responsive to reading out said table of contents from said temporary area and for controlling said writing means to write in said one portion of the recording area new data based upon said further desired information signal recorded in said predetermined area.
Claim 3
Dependent Claim
46 words
An optical disc recording apparatus according to claim 1, wherein when said control means detects that said table of contents data is already recorded on the recording area of said optical disc, said control means controls said writing means so that a recording operation is ended.
Claim 4
Dependent Claim
73 words
An optical disc recording apparatus according to claim 1, wherein when said control means detects that said table of contents data is not recorded on the recording area of said optical disc, said control means controls said reading means for reading out data from said temporary area outside of the recording area of said optical disc and controls said writing means to perform a recording operation on the basis of a reproduced result.
Claim 5
Dependent Claim
26 words
An optical disc recording apparatus according to claim 3, characterized in that said predetermined area is provided at the outer peripheral side of said recording area.
Claim 6
Dependent Claim
43 words
An optical disc recording apparatus according to claim 4, wherein said control means controls writing means such that, when it is detected by the reading means that said desired information signal is already recorded on said predetermined area, a recording operation is ended.
Claim 7
Dependent Claim
29 words
An optical disc recording apparatus according to claim 3, wherein said writing means writes information on said predetermined area that is the same as said table of contents data.
Claim 8
Dependent Claim
43 words
An optical disc recording apparatus according to claim 6, wherein said control means controls said writing means on the basis of a result from reproducing said predetermined area such that said writing means starts the writing operation from a previous writing ending point.
Claim 9
Dependent Claim
66 words
An optical disc recording apparatus according to claim 7, characterized in that said control means controls said recording apparatus such that, at the completion of recording operation, said recording apparatus records data based on an information signal recorded on said optical disc on one portion of said recording area together with data based on the information signal recorded on said optical disc by the previous recording.
Claim 10
Dependent Claim
26 words
An optical disc recording apparatus according to claim 8, characterized in that said predetermined area is provided at the inner peripheral side of said recording area.
Claim 11
Dependent Claim
58 words
An optical disc recording apparatus according to claim 3, wherein said control means controls the recording apparatus such that at the completion of first recording onto said optical disc, said recording apparatus records said data corresponding to an information signal recorded on said optical disc by said first recording on a predetermined area outside of said recording area.
Claim 12
Dependent Claim
26 words
An optical disc recording apparatus according to claim 10, characterized in that said predetermined area is provided at the inner peripheral side of said recording area.
