Abstract:
The present invention relates to a recording control apparatus and a recording control method which can improve the convenience of a storage medium and also to a program and a storage medium. Image annulus data or audio annulus data having a first data amount in accordance with a data amount required for reproduction for first reproduction time and low-resolution annulus data or frame-meta annulus data having a second data amount in accordance with a data amount required for reproduction for a second reproduction time that is different from the first reproduction time are recorded on an optical disk so that the data are periodically arranged. The image annulus data or the audio annulus data is extracted from a data series of corresponding video data or audio data. The low-resolution annulus data or the frame-meta annulus data is extracted from a data series of low-resolution that is video data having a less data amount or a series of frame metadata. Clip metadata generated in accordance with the frame metadata is recorded at random independently of those data. The present invention is applicable to a disk drive apparatus.
