Abstract:
A digital data recording and reproducing apparatus for recording or reproducing inputted digital data, comprising:a memory to temporarily store said inputted digital data;recording processing means for performing an encoding for error correction to the digital data read out from said memory and recording the encoded digital data onto a recording medium;reproduction processing means for reproducing said encoded signal recorded on said recording medium and performing a decoding of said error correction;confirming means for, when recording a signal onto said recording medium, instantaneously reproducing the recorded signal and confirming an error state of the signal recorded on said recording medium;drive control means for controlling a driving of said recording medium; anda system controller for controlling said memory, said recording processing means, said reproduction processing means, said confirming means, and said drive control means so that the signal is recorded onto or reproduced from said recording medium in response to a control signal that is selected,wherein said apparatus further comprises:retry means for controlling said memory, said recording processing means, and said drive control means when the signal is recorded onto said recording medium in a manner such that the digital data which had been stored in said memory and has already been read out for recording from said memory is again read out and is again recorded onto said recording medium by said recording processing means in accordance with a confirmation result of said confirming means and for controlling said reproduction processing means and said drive control means when the signal is reproduced from said recording medium in a manner such that an area on said recording medium which has already been reproduced is again reproduced in accordance with a result of said error correction by said reproduction processing means;mode selecting means for selecting a first processing mode and a second processing mode in accordance with a kind of said inputted digital data or said digital data which is reproduced from said recording medium; andretry processing control means for controlling on the basis of a selection result of said mode selecting means in a manner such that a retrying process by said retry means is executed in case of said first processing mode and the retrying process by said retry means is not performed in case of the second processing mode.
