Abstract

A method and apparatus for recording control for a recording medium having a data recording region for recording data such as audio data, speech data, and a control data region for recording control data for the data recording region. The method and apparatus includes identifying a non-silent recorded portion and a silent recorded portion of the data recorded in the data recording region based upon the signal level of the data recorded in the data recording region, and recording control data for separating the data recorded in the data recording region into temporally former and temporally latter portions at a boundary portion between the non-silent recorded portion and the silent recorded portion based upon the results of the identification after recording of the data in the data recording region has ended.

Claims

1. An apparatus for recording a first program of inputted data during a recording operation to a recording medium having address data pre-recorded thereon and also having a data recording region for recording said inputted data based upon said address data and a control data region for recording control data for said data recording region, said apparatus comprising:

storage means for storing an address if the signal level of the inputted data becomes lower than a pre-set level;

recording control means for stopping the recording operation and

editing means for editing the recording control data in the control region for separating, from the recorded first program of inputted data, inputted data recorded downstream of the address stored in said storage means as invalid recorded data based upon the address data stored in said storage means;

wherein upon a subsequent recording operation, a second program of inputted data is recorded to the recording medium in succession to said first program thereby deleting said invalid recorded data.

2. The apparatus of claim 1, wherein the invalid recorded data is a silent portion of the first program of inputted data.

3. An apparatus for recording a first program of inputted data during a recording operation to a recording medium having address data pre-recorded thereon and also having a data recording region for recording said inputted data based upon said data and a control data region for recording control data for said data recording region, said apparatus comprising:

storage means for storing an address if the signal level of the inputted data becomes lower than a pre-set level;

recording control means for stopping the recording operation; and

editing means for editing the recording control data in the control region for separating the data recording region into a data recorded region that contains the inputted data recorded upstream of the address stored in the storage means, and into a data recorded region that contains the inputted data recorded downstream of the address stored in said storage means;

wherein upon a subsequent recording operation, a second program of inputted data is recorded to the data recordable region of the recording medium in succession to the first program thereby deleting the inputted data recorded downstream of the address stored in said storage means.

4. The apparatus according to claim 3, wherein the inputted data recorded downstream of the address stored in said storage means is a silent portion of the first program of inputted data.
