Description

A kind of CD drive

Technical field

The present invention relates to CD-ROM drive field, more particularly to a kind of CD drive.

Background technology

CD drive abbreviation CD-ROM drive, for being written and read to CD.CD-ROM structure includes optical pick-up unit, Abbreviation OPU (Optical Pick-up Unit) and servo-control system, optical pick-up unit are also laser head, It includes laser, photoelectric detector and optics.Optical pick-up unit is the read-write system of CD, is read When going out, the laser beam that it is emitted is irradiated on the concavo-convex reflective surface of CD, after being reflected by reflector layer, warp The laser beam that photoelectric detector will reflect back into is converted to analog signal, then obtains signal after being handled through electronic circuit Coding, encodes the data just read after decoding；During write-in, launch the laser Jing Guo signal modulation and arrive Imprinting is carried out to CD on blank CD.

Common CD drive is merely able to a face of writable disc, so if needing the another of writable disc Simultaneously, it is necessary to CD is exited from CD-ROM drive, CD-ROM drive is re-fed into after upset, by CD ROM read-write CD Another face, the reading/writing method for taking both-sided optical disc the above traditional is not only cumbersome, the read-write of CD Efficiency is low, increases the time cost and human cost of CD read and write, except this, and traditional both-sided optical disc is read and write Method adds both-sided optical disc by human hand or the number of times for the device turning operation that turns over, and increases both-sided optical disc and is drawn Wound or defaced probability, the information for being easily caused both-sided optical disc are lost.

There is a kind of CD drive with two optical pick-up units in the prior art, it is not necessary to overturn light Disk is that the positive and negative that can realize the CD to sending into the CD drive is written and read, but is still avoided not The operation of CD-ROM drive is sent into afterwards to first capturing for CD, in today of information security attention, both-sided optical disc Closure and confidentiality seem increasingly important, the CD-ROM drive of existing double optics pickup unit can not expire well The confidentiality of sufficient both-sided optical disc, in the prior art in the absence of need not capture CD or upset CD i.e. can be achieved pair CD carries out the CD drive of two-sided read-write.

The content of the invention

To overcome the deficiencies in the prior art, the purpose of the present invention is：A kind of CD drive is provided, using double Optical pick-up unit, can be to being stored in optical disk cartridge in the case where that need not overturn CD or optical disk cartridge CD carries out two-sided read-write, easy to operate, improves the read-write efficiency of both-sided optical disc, the CD drive It is automatic that CD is promoted into read-write region, protect CD not touched by external force, improve CD and storing and reading and writing During security.

In order to solve the technical problem in background technology, the invention provides a kind of CD drive, including push away Enter the box body that mechanism, read write device, controller and front end are provided with opening, the propulsive mechanism and read write device It is disposed side by side in the box body, the propulsive mechanism is close to the openend of box body, and the read write device is remote The openend of box body,
