Embodiment Construction

[0022] Embodiments of the present invention will be described below with reference to the accompanying drawings. figure 1 It is a block diagram showing the state of implementing the video recording apparatus of the present invention. In this embodiment, a device capable of handling both an optical disk such as a DVD-R and a hard disk (DVD-VR recorder with HDD) is described as a recording device. However, a semiconductor memory or the like can also be used as the recording medium when necessary. exist figure 1 In , the device roughly consists of a recording unit block on the left and a playback unit block on the right.

[0023] figure 1 The video recording device shown in has two different types of optical drive units. First, the video recording apparatus includes an optical disk drive for reading / writing information by rotatably driving an optical disk (DVD-RAM, DVD-RW, or DVD-R) 1001 serving as a first medium, that is, an information recording medium on which a video file...

Abstract

The present invention discloses a write-once medium having a limited storage capacity that can be efficiently used. When a plurality of recording areas (Rzone 3, 4, 5) are sequentially formed from the lead-in side to the lead-out side, the first digital content (<7> real-time data 2) and the first management information (<8> change file / VAT_ICB ) of the first digital data is recorded in at least one (Rzone 4) of the plurality of recording areas. Next, without closing the recording zone (Rzone 4), second digital data including second digital content (<10> real-time data 3) and second management information (<11> change file / VAT_ICB) is recorded. Thereafter, the recording zone (Rzone 4) is closed (<12> Rzone closed).

Description

technical field [0001] The present invention relates to a recording method of a WORM recording medium such as a write-once medium such as a DVD-R disc, and more particularly to a method and apparatus for efficiently using a write-once medium having limited storage capacity. Background technique [0002] The DVD-Video format used in DVD software sold as a unit (or as a package), or the DVD-VR format used in a DVD recorder to perform editing processing can be used as the video recording format of a Digital Versatile Disc (DVD). Conventionally, the DVD-VR format is mainly used on DVD-RAM or DVD-RW (Japanese Patent Application Laid-Open Publication No. 9-259538). [0003] These DVD-RAM and DVD-RW are rewritable media that advantageously perform editing processing. However, the unit cost of these media is relatively high. In contrast, the cost of DVD-R is relatively low. Conventionally, information is mainly recorded on DVD-R in the DVD-Video format, since playback compatibili...
