Abstract

Abstract A dubbing apparatus for reproducing plural pieces of music recorded on an optical disc and a recording device for recording the reproduced music signals supplied from the reproducing device onto a magnetic tape. When the total recorded time of music on the disc is longer than the recordable time of the magnetic tape, the recording device stops recording each time the reproduction of each piece of music is finished, rewinds the magnetic tape for a specified period of time, and then starts recording the next piece of music while performing fade-in and fade-out actions on the two adjacent pieces of music during this overlapped recording period, thereby reducing the overall music recording time. This allows all pieces of music on the disc to be dubbed into the magnetic tape within the recordable time of the latter.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 195 words
A dubbing apparatus for audio equipment comprising: a reproducing device for reproducing a plurality of pieces of music recorded on one of an optical disk and a digital audio tape and outputting the reproduced music as music signals; and a recording device having a magnetic head circuit for dubbing the reproduced music signals to a magnetic tape, said recording device stopping a recording operation each time the reproduction of each piece of music is completed, rewinding the magnetic tape for a duration equal to the sum of a reduction time of the recorded piece of music and a cross fade time, and restarting the recording operation form the rewound position, wherein the music signal of a next piece of music is reproduced by the reproducing device while at the same time gradually lowering the recording level of the previously recorded piece of music for the duration of the cross fade time, thus overlapping the two adjacent pieces of music in the cross fade time, said reduction time representing a portion of each reproduced music piece which is deleted from each corresponding recorded music piece, to enable all of said reproduced music pieces to be re-recorded.
Claim 2
Dependent Claim 195 words
A dubbing apparatus for audio equipment comprising: a reproducing device for reproducing a plurality of pieces of music recorded on one of an optical disk and a digital audio tape and outputting the reproduced music as music signals; and a recording device having a magnetic head circuit for dubbing the reproduced music signals to a magnetic tape, said recording device stopping a recording operation each time the reproduction of each piece of music is completed, rewinding the magnetic tape for a duration equal to the sum of a reduction time of the recorded piece of music and a cross fade time, and restarting the recording operation form the rewound position, wherein the music signal of a next piece of music is reproduced by the reproducing device while at the same time gradually lowering the recording level of the previously recorded piece of music for the duration of the cross fade time, thus overlapping the two adjacent pieces of music in the cross fade time, said reduction time representing a portion of each reproduced music piece which is deleted from each corresponding recorded music piece, to enable all of said reproduced music pieces to be re-recorded.
Claim 3
Dependent Claim 28 words
A dubbing apparatus as claimed in claim 1, wherein said reduction time of the recorded piece of music is a single common value for all pieces of music.
Claim 4
Dependent Claim 31 words
A dubbing apparatus as claimed in claim 1, wherein said reduction time of the recorded piece of music is made proportional to the playback time of the individual pieces of music.
Claim 5
Dependent Claim 23 words
A dubbing apparatus as claimed in claim 1, wherein said cross fade is generated by a bias control of said magnetic head circuit.
Claim 6
Dependent Claim 26 words
A dubbing apparatus as claimed in claim 1, wherein said recording device repeats said stopping, rewinding and restarting operations between each of said reproduced music pieces.
Claim 7
Dependent Claim 40 words
A dubbing apparatus as claimed in claim 1, wherein said reduction time is based upon a difference between a total reproduction time for the plurality of musical pieces to be reproduced and a total recording time of said magnetic tape.
Claim 8
Dependent Claim 24 words
A dubbing apparatus as claimed in claim 1, further comprising an operation unit for manually entering a total recording time of said magnetic tape.
Claim 9
Dependent Claim 64 words
A dubbing apparatus as claimed in claim 1, further comprising: memory for storing an amount of recordable time remaining on the magnetic tape and a total playback time for the plurality of music pieces, and a controller for determining the reduction based upon a comparison between the recordable time and the playback time minus a cumulative cross fade time between each piece of music.
