Embodiment Construction

[0058] refer to Figure 1 to Figure 22 , with reference to the synchronization method in the recorder device according to the present invention, the configuration of the recorder device according to the present invention and the outline of the operation of the recorder device will be described.

[0059] Since the drive device included in the recorder device according to this embodiment is realized as a device that writes data to or reads data from an optical disc, it is hereinafter referred to as an optical disc drive device. As the optical disc, BD (Blu-ray Disc), DVD (Digital Versatile Disc), CD (Compact Disc), and the like are assumed. However, the present invention is not limited thereto, and is generally applicable to drive devices for writing data into detachable recording media such as floppy disks and magneto-optical disks.

[0060] Next, the configuration of the recorder device according to the present invention and the outline of the operation of the recorder device...

Abstract

Provided is a drive device that reduces the time needed to write content data from a nonremovable recording medium to a removable recording medium, which occurs when content data is written to a nonremovable recording medium in order to write to a user-specified removable recording medium. The drive unit (300) of a recording device (100) of this invention is provided with a drive controller (320) that, upon receiving a write command indicating that data should be written to a specific area of the specified disk, writes the data to a memory unit (340) and records an association between the area of the memory unit (340) to which the data was written and the specific area of the specified disk. When the specified disk is inserted, the drive controller writes, to the specific area of the specified disk, the data which had been written to the memory unit (340), and also sends a data write complete notification to the issuer of the write command.

Description

technical field [0001] The present invention relates to a drive device including a non-removable recording medium and capable of loading a detachable recording medium, a synchronization method of the drive device, and a content recording and playback device including the drive device. Background technique [0002] With the popularization of television receivers capable of high-definition display such as so-called full high-definition televisions, recorder devices that can be loaded with Blu-ray discs (BD) that can record large-capacity video programs such as full high-definition television programs are also becoming popular. data. [0003] Recorder devices capable of loading optical discs represented by BD can be roughly divided into two types, one of which has a built-in hard disk (hybrid recorder device) capable of recording data larger than that of an optical disc, and the other does not have the above-mentioned hard disk (direct recorder device). [0004] Since the dir...
