Abstract
Abstract A recording and reproducing system which can automatically repair, when an abnormal condition of production occurs, the abnormal condition in a recording condition without manual operation-of an operator. When an abnormal condition of a reproduction signal from a compact disc is detected, the compact disc is reproduced again beginning with a head portion of a data block being currently reproduced or a portion immediately forwardly of such head portion, and reproduction signal then is recorded again from a head portion of a data block being currently recorded by digital signal recording and reproducing means or a portion immediately forwardly of the head portion.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
190 words
A recording and reproducing system comprising: compact disc reproducing means for reproducing a signal recorded on a compact disc in a reproduction process so as to provide a reproduction signal; digital signal recording and reproducing means for recording the reproduction signal from said compact disc reproducing means and for reproducing the thus recorded reproduction signal; means for separating data blocks of the reproduction signal from said compact disc reproducing means; abnormal reproduction detecting means for detecting an abnormal condition in said reproduction signal reproduced in said reproduction process from a signal recorded on a compact disc at the compact disc reproducing means; means for causing, when said abnormal condition is detected, said compact disc reproducing means to return to a head portion of the data block currently being reproduced or a portion immediately forward of said head portion and re-initiate reproduction of said data block; and means for causing, when said abnormal condition is detected, said digital signal recording and reproducing means to, beginning with the head portion of the data block currently being recorded or a portion immediately forward of said head portion, re-initiate recording of said reproduction signal.
Claim 2
Dependent Claim
190 words
A recording and reproducing system comprising: compact disc reproducing means for reproducing a signal recorded on a compact disc in a reproduction process so as to provide a reproduction signal; digital signal recording and reproducing means for recording the reproduction signal from said compact disc reproducing means and for reproducing the thus recorded reproduction signal; means for separating data blocks of the reproduction signal from said compact disc reproducing means; abnormal reproduction detecting means for detecting an abnormal condition in said reproduction signal reproduced in said reproduction process from a signal recorded on a compact disc at the compact disc reproducing means; means for causing, when said abnormal condition is detected, said compact disc reproducing means to return to a head portion of the data block currently being reproduced or a portion immediately forward of said head portion and re-initiate reproduction of said data block; and means for causing, when said abnormal condition is detected, said digital signal recording and reproducing means to, beginning with the head portion of the data block currently being recorded or a portion immediately forward of said head portion, re-initiate recording of said reproduction signal.
Claim 3
Dependent Claim
74 words
The recording and reproducing system as claimed in claim 1, further comprising no-sound detecting means for detecting, when an abnormal condition is detected, whether or not a portion of said reproduction signal immediately forward of the data block currently being reproduced is in a no-sound condition, and means for providing, when said portion is not in a no-sound condition, a no-sound period to the portion when the reproduction of said reproduction signal is re-initiated.
Claim 4
Dependent Claim
74 words
The recording and reproducing system as claimed in claim 1, further comprising no-sound detecting means for detecting, when an abnormal condition is detected, whether or not a portion of said reproduction signal immediately forward of the data block currently being reproduced is in a no-sound condition, and means for providing, when said portion is not in a no-sound condition, a fade-in period to the portion when the reproduction of said reproduction signal is re-initiated.
Claim 5
Dependent Claim
61 words
The recording and reproducing system as claimed in claim 1, further comprising means for counting a number of times an abnormal condition is detected with regard to the same data block and stopping the reproducing and recording operations of said compact disc reproducing means and said digital signal recording and reproducing means when the number of times reaches a predetermined number.
Claim 6
Dependent Claim
60 words
The recording and reproducing system as claimed in claim 1, further comprising means for accumulating time required for detection of an abnormal condition with regard to the same data block and stopping reproducing and recording operations of said compact disc reproducing means and said digital signal recording and reproducing means when the accumulated time reaches a predetermined period of time.
