Problems solved by technology

When using the traditional optical power calibration jig to perform the calibration action, since it is impossible to directly perform optical power calibration on the DVD recorder integrated in the optical disc recorder, the calibration action using the traditional optical power calibration jig often has relatively difficult large error exists

Abstract

An optical power-correcting tool is used on one optical disk access unit of optical disk recorder to make optical disk recorder correcting optical power. Optical disk access unit has one optical reading head for transmitting one light beam for writing information in one optical disk. Said Optical power correcting tool includes one bracket, one positioning device and one optical sensor, wherein positioning device for fixing bracket on optical disk access unit, optical sensor configured on bracket, when making optical power correcting, optical power correcting tool set on optical disk access unit, optical sensor being opposite to optical reading head to make optical sensor sensing optical reading head transmitted light beam optical power, to generate electrical signal, optical disk recorder according to electrical signal making optical power correcting.

Description

technical field [0001] The present invention relates to an optical power calibration jig, and in particular to an optical power calibration jig used in an optical disc video recorder. Background technique [0002] With the advent of DVD-R / W (Digital Versatile Disc Recordable / Re-Writeable) burners and the sharp increase in the popularity of DVD players, DVD Recorders (DVRs) have gradually become the preferred choice of VCRs. mainstream. In addition to dubbing old VHS (video homesystem) tapes to CD-R (Compact Disk-Recordable), CD-RW, DVD-R or DVD-R / W, CD recorders can also record any channel in real time or in advance TV shows on CD-ROM. [0003] Today's CD recorders are usually obtained by integrating a general DVD burner into the CD recorder. In order to make the optical disc recorder operate normally, optical power calibration must be performed before leaving the factory. [0004] However, the current optical power calibration fixture can only be used for optical power ...
