Embodiment Construction

[0042] An information recording method, an information recording apparatus, and a recording medium of the present invention will be described in detail with reference to the drawings.

[0043] like figure 1 As shown, the information recording device is a disk camera system, in which there is a DV camera 1 for selecting an imaging picture of an object as a DV signal, such as DCR-TRV 7 produced by Sony Corporation, the camera complies with the DV standard, An AV microcomputer system 10 for processing the DV signal received from the DV camera 1, a mode setting commander 8 for setting the instruction mode to the RISC CPU 3 of the AV microcomputer system 10, and a display 7 for The screen of the DV camera 1 is monitored.

[0044] The DV video camera 1 is a video camera which images a subject through an optical system such as a lens or a CCD, encodes the resulting image signal with an encoder / decoder 1a and outputs the resulting signal to a DV terminal.

[0045] The AV microcomput...

Abstract

In an information recording device, variable-speed reproduction by software control is to be enabled. To this end, the information recording device has an HDD for recording an audio/visual digital data stream with a logical sector as an accessing unit, and an AV micro-computer system 10. This AV micro-computer system 10 has, as a recording data unit, a fixed length of the audio/visual digital data stream corresponding to an integer number multiple of a frame length. The AV micro-computer system 10 allocates the recording data unit to a minimum number of the logical sectors that can record the recording data unit in its entirety, while stuffing dummy data in the remaining portion of a logical sector of the digital data stream.

Description

technical field [0001] The present invention relates to an information recording method and apparatus for recording audio and / or image digital data streams on a disc-shaped recording medium, and a recording medium. Background technique [0002] As hard disk drives have increasingly become peripheral devices for personal computers, technical improvements in hard disk drives have mainly involved random access of so-called discrete text data as quickly as possible with high reliability. [0003] In order to keep up with recent developments in multimedia, there is a demand for an HDD and a host system that allow an inexpensive structure of a so-called AV HDD system, so that, in addition to AV streams, for example, an HDD having a transfer rate of 28.6 Mbps (megabits per second) Digital video (DV system SD) standards, or audiovisual (AV) digital data streams of MPEG 2 (Moving Picture Experts Group 2) with a maximum transfer rate of 15 Mbps, as well as random access data, can be a...
