[0053] A first embodiment of the present invention will be described with reference to the drawings. The optical disc drive according to the present invention is a portable video recorder intended to record picked-up images on a DVD disc.

[0054] The optical disk drive 1 using the present invention has Figure 4 structure shown. This optical disk drive includes: a video input block 3 that performs analog-to-digital conversion on a video signal captured by an image pickup device (not shown) or a video signal supplied from an external device to provide video data. It should be noted that the plurality of pickup devices included in the optical disc drive 1 are controlled by the microcomputer 4 also included in the optical disc drive 1 to provide imaging results consisting of moving images or still images. Thus, the video input block 3 operates in response to the control of the pickup device by the microcomputer 4, selectively receiving video data composed of moving images or st...

[0173] A third embodiment according to the present invention will be described below.

[0174] Compared with the previous description with reference to Figure 7, Figure 16 Used to describe how to record intermediate management information. In the third embodiment of the optical disk drive according to the present invention, as indicated by arrows, the management information of all the extended files that have been recorded in the optical disk so far is distributed as intermediate management information to be recorded together with the extended files.

[0175] from Figure 16 It can be seen that as long as the intermediate management information recorded at the end of the recording area is reproduced, the management information of all intermediate files recorded on the optical disc, such as addresses, can be obtained, and the operation of searching for the intermediate management information can be correspondingly simplified.

Abstract

An optical disc device capable of recording a moving picture as well as a still image file other than the moving picture. The optical disc device includes: a microcomputer (4) for generating information on controlling a file to be recorded; recording means having a DVD signal processor (14) for combining the file to be recorded and control information corresponding to the file and recording the combined set on a program area of an optical disc, a random access memory (15), an analog front end portion (16), a motor amplifier (18), an optical head (19), and a spindle motor (20); and the microcomputer (4) functioning as control means for controlling operation of the microcomputer (4) constituting at least control information generation means and the recording means. According to a file attribute, the microcomputer (4) switches the file and the control information recording format for the program area.

Description

technical field [0001] The present invention relates to a recording device, a recording method, a recording program, and a recording medium in which the recording program is recorded. For example, the present invention can be applied to DVD (Digital Versatile Disc). According to the present invention, files of still images can be recorded in addition to moving images by selecting the format of management information to be recorded with the files according to the attributes of the files. According to the present invention, a standard optical disc drive can also be used to verify the content of a file recorded on an optical disc in addition to a moving image, for example, a file recorded on an optical disc according to a format selected for the file. [0002] This application claims priority from Japanese Patent Application No. 2002-124604 filed on Apr. 25, 2002, the entire contents of which are hereby incorporated by reference. Background technique [0003] Generally, exist...
