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 at least a first program and a second program of inputted data in a data recording operation on a recording medium having a data recording region for recording the inputted data and a control data region for recording control data for said data recording region, said apparatus comprising:

time measurement means for measuring the time during which the signal level of the inputted data of the first program recorded in said data recording region is below a pre-set level; and

recording control means for automatically discontinuing the data recording operation of the first program when the time measured by said time measurement means exceeds a pre-set time duration, and for deleting, before the second program is recorded, at least a portion of a silent portion of the first program recorded during said pre-set time duration by recording control data in the control data region which defines the end of the first program as being at a time point that precedes the end of said pre-set time duration, wherein said second program is recorded in the data recording region starting from said time point.

2. The apparatus of claim 1 wherein the time point precedes the end of the pre-set time duration by a predetermined amount of time.
