Audio data recording/reproduction device having digital high speed dubbing function and audio data dubbing system using such devices

A disc reproduction device used in an audio data dubbing system, said audio data dubbing system including said disc reproduction device, and a disc recording device for first storing into a recording side memory compressed audio data for recording provided from said disc reproduction device and reading out the stored data intermittently therefrom on the basis of a predetermined recording unit to be recorded in a recording side disc,

• wherein said disc reproduction device comprises:
• means for reproducing compressed audio data intermittently on the basis of a predetermined reproducing unit from said reproduction side disc,
• a reproduction side memory for storing said intermittently reproduced compressed audio data,
• means for detecting the data amount in said reproduction side memory,
• means for reading out continuously said compressed audio data from said reproduction side memory to provide the read out data as said compressed audio data for recording,
• means for detecting failure of reproduction of said compressed audio data from said reproduction side disc to retry the reproduction operation, and
• means responsive to an output of said data amount detecting means for suspending the recording operation of said compressed audio data for recording to said recording side disc in said disc recording device when the data amount in said reproduction side memory is reduced to become less than a reference value that is lower than the capacity of said reproduction side memory by more than a predetermined unit.

An audio data dubbing system, comprising:

• a disc reproduction device, and
• a disc recording device,
• wherein said disc reproduction device includes:
• means for reproducing intermittently from a reproduction side disc compressed audio data on the basis of a predetermined reproducing unit,
• a reproduction side memory for storing said intermittently reproduced compressed audio data,
• first data amount detecting means for detecting the data amount in said reproduction side memory,
• means for reading out continuously said compressed audio data from said reproduction side memory to provide the read out data as compressed audio data for recording, and
• means for detecting failure of reproduction of said compressed audio data from said reproduction side disc to retry the reproduction operation,
• wherein said disc recording means includes:
• recording side memory for storing said compressed audio data for recording provided from said disc reproduction device,
• second data amount detecting means for detecting the data amount in said recording side memory,
• means responsive to an output of said second data amount detecting means for reading out said compressed audio data for recording from said recording side memory and recording the read out data intermittently in a recording side disc when the data amount in said recording side memory reaches a predetermined recording unit,
• means for detecting failure of recording of said compressed audio data for recording to said recording side disc to retry the recording operation, and
• means responsive to an output of said second data amount detecting means for suspending the reproduction operation of said compressed audio data from said reproduction side disc in said disc reproduction device when the data amount in said recording side memory increases to exceed a first reference value that is greater than said predetermined recording unit and smaller than the capacity of said recording side memory,
• wherein said disc reproduction device further comprises means responsive to an output of said first data amount detecting means for suspending the recording operation of said compressed audio data for recording to said recording side disc in said disc recording device when the data amount in said reproduction side memory is reduced to become lower than a second reference value that is lower than the capacity of said reproduction side memory by more than a predetermined unit.
