Audio data recording/reproduction device having digital high speed dubbing function and audio data dubbing system using such devices
First Claim
1. A disc recording device used in an audio data dubbing system, said audio data dubbing system including a disc reproduction device for reproducing intermittently from a reproduction side disc compressed audio data on the basis of a predetermined reproducing unit to be stored in a reproduction side memory and then reading out the stored data therefrom continuously to be provided as compressed audio data for recording, and said disc recording device,wherein said disc recording device comprisesa recording side memory for recording said compressed audio data for recording provided from said disc reproduction device,means for detecting the data amount in said recording side memory,means responsive to an output of said 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 said compressed audio data for recording to said recording side disc for retry of a recording operation, andmeans responsive to an output of said 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 reference value that is greater than said predetermined recording unit and smaller than the capacity of said recording side memory.

Abstract
An audio data dubbing system includes a reproduction side device and a recording side device. The reproduction side device reproduces intermittently from a reproduction side disc compressed audio data on the basis of a predetermined reproducing unit, which is first stored in a reproduction side memory and read out continuously therefrom to be provided as compressed audio data for recording. Recording side device first stores in a recording side memory compressed audio data for recording provided from the reproduction side device and reads out the same therefrom intermittently in a predetermined recording unit to be recorded on a recording side disc. The recording side device suspends the reproduction operation of compressed audio data from the reproduction side disc in the reproduction side device when the data amount in the recording side memory is increased to exceed a first reference value. The reproduction side device suspends the recording operation of the compressed audio data for recording to the recording side disc in the recording side device when the data amount in the reproduction side memory is decreased to become lower than a second reference value.
