Patent ID: 7433583

Claim:
A recording apparatus comprising: recording and reproducing means for recording and reproducing on and from a disk-like recording medium a moving image data file including moving image data, audio data relating to the moving image data, and after-recording audio data to be reproduced in parallel to the moving image data instead of the audio data relating to the moving image data; detection means for detecting a defective area in the disk-like recording medium in accordance with defective area information recorded on the disk-like recording medium, wherein the moving image data recorded in the defective area is unable to be normally reproduced; and control means for determining minimum sizes of continuous data areas for the moving image data file and the after-recording audio data on the basis of a data rate of the moving image data to be recorded by the recording means, a data rate of the after-recording audio data, and the defective area detected by the detection means, and controlling the recording and reproducing means so as to record the moving image data file and the after-recording audio data in accordance with the minimum continuous data area sizes, wherein the recording and reproducing means includes a head for recording data on the disk-like recording medium, and seeking means for seeking a position on the disk-like recording medium in which the data is to be reproduced by the head, and assuming that a seek time of the head is Tj, a rate at which data is read out from the disk-like recording medium is St, the data rate of the moving image data is Sv, the data rate of the after-recording audio data is Sa, a size of a defective area contained in the continuous data area for the moving image data is Dv, and a size of a defective area contained in the continuous data area for the after-recording audio data is Da, then a minimum recording time Tv of the moving image data, a minimum recording time Ta of the after-recording audio data, a minimum recording size Lv of the moving image data, and a minimum recording size La of the after-recording data are expressed as follows: Tv = 3 × Tj + Dv / St + Da / St 1 - Sv / St - Sa / St Ta = 3 × Tj + Da / St + Dv / St 1 - Sv / St - Sa / St Lv=Sv×Tv+Dv La=Sa×Ta+Da.
