Abstract

Disclosed is a disk recording and reproduction apparatus for recording and / or reproduction of optical disks of multiple different formats impossible to record or reproduce with a single pickup. A disk recording and reproduction apparatus containing a base unit (25) with two separate optical pickups (31) and (32) corresponding to two different format types and installed around the center of a turntable (27) for rotating a disk.

Description

technical field [0001] The present invention relates to a disc recording and reproducing apparatus, and more particularly, to a disc recording and reproducing apparatus for recording and / or reproducing by an optical pickup while rotating a disc recording medium. Background technique [0002] Disk recording and reproducing apparatuses are widely used to perform recording or reproduction by using an optical pickup while rotating a disk recording medium. In the prior art in this field, an optical pickup constituting a disk recording medium is accessed by an optical pickup by rotating the optical disk on a turntable and moving the optical pickup in a radial direction of the optical disk, and specific recording or reproduction is performed. [0003] The laser wavelength of the optical pickup varies according to the optical disc format. For example, in the case of a CD (Compact Disc), laser light with a wavelength of 780 nm (nanometer) is used. However, DVDs use lasers with a wa...
