Description

一种光碟读写设备以及用于该设备光头的制造调控方法 One kind of disc read-write device and a method for regulating the apparatus for producing optical head

技术领域 FIELD

本发明涉及一种包括由光碟托架、光头、旋转电机头构成的光碟读写设备, 尤其涉及该光碟读写设备的光头结构。 The present invention relates to a disc comprising a bracket, an optical head, the head configuration of the rotary electric machine disc read-write device, particularly to a structure of an optical head of the disc reader apparatus. 另外还涉及用于该光碟读写设备的光头的制造调控方法。 Also it relates to a method of manufacturing a regulation of the CD read-write head of the device.

背景技术 Background technique

目前,光碟作为人类现代信息存储和流通的最重要手段,但由于棵露光碟的直接使用,导致光碟从光碟盒、光碟读写设备中反复的取出或放入时,很快^皮磨损划花成为一种必然。 Currently, modern information storage and CD-ROM as the most important means of human circulation, but due to the direct use of trees exposed disc, resulting in a disc repeatedly taken in and out from the CD box, CD read-write device, and soon wear leather scratching ^ become a necessity.

光碟一般都是采用单面保存数据,而仅给光碟最容易磨损划花的透光面设计套加一个单面护碟盒,对光碟的透光面自始至终实施单面贴紧遮蔽保护,既从根本上解决了光碟容易磨损划花的难题,同时还不增加光碟的厚度与体积, 使得被保护后的光碟在使用中仍然轻巧方便。 Using single-sided discs are typically stored data, only the most likely to wear to the disc scratching plus a translucent surface designed sets sided retaining disc cartridge, the disc of translucent surface adhesion sided masking throughout embodiment, both from fundamentally solve the problem of scratching the disc is easy to wear, but do not increase the thickness and volume of the disc, making the disc after the protected still light and easy to use. 读碟使用时,套有单面护碟盒的光碟与单面护碟盒可以一同放入光碟读写设备使用。 When using its reading, single-sided sleeve retaining single-sided DVD disc cartridge can be placed in guard disc cartridge used with a disc reader apparatus.

我从2001年至今,七年来一直在致力于上述这种光碟无磨损保护技术的研究和改进工作,并以传统只能读取棵露光碟的光碟读写设备为基础,提出了多套可行制造方案,其中一套方案包括单面护碟盒设有光头读写窗,利用传统读取棵露光碟的光碟读写设备的光头,通过透过该单面护碟盒的光头读写窗读写光碟。 I Since 2001, seven years have been devoted to research and improve the work above this disc wear protection technology, and can only be read with a traditional trees exposed disc CD read-write device is proposed based on several sets of feasible manufacturing scheme, which scheme comprises a single-sided disc cartridge is provided with an optical head to read and write protection window, use a conventional optical head reads the trees exposed DVD disc read-write device by reading and writing through the read window sided disc cartridge head guard CD. 但是传统读取棵露光碟的光碟读写设备的光头,其结构还包括与旋转电机头固定并共用一个动力装置实施升降,读碟使用时,光头和旋转电机头同时由所述动力装置提供动力分别穿过光碟托架的光头读写槽和光碟托架的旋转电机头孔后读写光碟。 However, the conventional optical head reads the trees exposed DVD disc read-write device, the structure of the rotary electric machine further comprises a fixed head and a common power lifter apparatus embodiment, when its reading using the optical head and the head while rotating electric machine powered by the power means after passing through the disc are write head bracket slot holes and the rotating electric machine head carriage write CD disc. 而当套有单面护碟盒的光碟一同放在光碟托架进仓使用后, 单面护碟盒将封闭光碟托架的光头读写槽,于是传统读取棵露光碟的光碟读写设备的光头结构将撞击到单面护碟盒而不能实现正常工作,甚至损坏光头,同时也还将阻碍旋转电机头穿过光碟托架的旋转电机头孔将光碟顶起旋转,所以传统读取棵露光碟的光碟读写设备的光头结构并不能直接用于读写套有设有光头读写窗的单面护碟盒的光碟。 When the one-side protective sleeve CD disc cartridge on the disc together with the carriage after Jincang use, single-sided disc cartridge retaining groove closure disc read-write head carriage, so exposed trees conventional CD disc reading device to read and write the optical head structure impinging sided disc cartridge can not be achieved protection work, or even damage the head, while the rotary electric machine will hinder the rotary electric machine head through the first hole of the CD disc from the top bracket to rotate, so the traditional reading trees the optical head structure exposed disc CD read-write device for reading and writing can not be directly set single-sided disc cartridge retaining a disc with the optical head to read and write windows.

虽然我也在我已经申请的多个专利方案中预示了可以利用传统读取棵露光碟的光碟读写设备的光头结构来透过单面护碟盒的光头读写窗读写光碟,但都没具体设计出实际的可实施方案。 Although the number of patents scheme I also I have applied in foreshadowed can read using the optical head structure traditional trees exposed disc CD read-write device to read and write head through the window to read and write single-sided DVD disc box protection, but all no specific design may be a practical embodiment.

发明内容 SUMMARY

鉴于现有技术的以上不足,本发明设计的目的是: In view of the above deficiencies of the prior art, an object of the present invention is designed to:

提供一种光碟读写设备,该光碟读写设备所设置的光头结构是利用传统光碟读写设备的光头结构的直接改进,改进后的光头能在,光碟托架运送套有单面护碟盒的光碟进仓后,实现透过单面护碟盒的光头读写窗正常读写光碟,并且还不影响旋转电机头的正常顶碟工作; To provide a disc reader apparatus, the structure of the optical head disc reader apparatus is provided to improve the direct reading and writing apparatus using a conventional DVD optical head structure, the optical head can have improved in, CD transport carriage protection cover sided disc cartridge after binning disc, read and write window through normal DVD write head care sided disc cartridge, and does not affect the normal work of the top plate of the first rotating electrical machine;

另外,在上述目的基础上,同时再进一步的改进光碟托架并使其光碟托架的水平承载强度更可靠; Further, on the basis of the above-described object, while further improving the carrier disc and the carrier disc so that the horizontal bearing strength is more reliable;

最后,还具体提供两种适用上述两种目的光碟读写设备的光头的制造调控方法,以实现光头能正常读写到光碟的数据。 Finally, specific regulation provides a method suitable for producing two kinds of the two disc read-write device object of the optical head, the optical head can read and write in order to achieve the normal data to the disc. 为实现上述三个目的,本发明采用了以下技术方案: To achieve the above three objectives, the present invention employs the following technical solution:

设计一种透过单面护碟盒的光头读写窗读写光碟的光碟读写设备,作为本发明第一种优选方案,以实现第一个发明目的。 Design of a DVD disc reader read window read-write device via an optical head guard sided disc cartridge as a first preferred embodiment of the present invention, in order to achieve the first object of the invention. 该光碟读写设备除了包括光碟托架、光碟托架的光头读写槽、光头、旋转电机头等传统光碟读写设备普遍具有的部件以外,在套有光碟的单面护碟盒置放在光碟托架进仓后且光头读写光碟时,所述光头位于其单面护碟盒的背面或者与光碟托架的置放面平齐,该光头的读写面与单面护碟盒的背面相对应,为此该光头的读写面低于单面护^5莱盒的背面,从而使光头不会撞击到单面护碟盒的背面,同时保障旋转电机头也能正常穿过光碟托架的旋转电机头孔和单面护碟盒的顶碟孔将光碟顶起旋转;由于单面护碟盒的背面是需要放置到光碟托架的置放面上使用的,所以一般情况下,两者实际都是相对位于在同一个平面位置上,作为参照面时任选其一都可; 由于光头与旋转电机头一般都同时固定在同一个动力装置上实施升降,所以可以通过将光头所设置在动力 In addition to the optical disc apparatus comprises a CD reader bracket groove disc reader head carriage, an optical head, the rotary electric machine class conventional CD reader device generally have a member other than the one surface of the enclosure has a disc retaining disc placed in the disc when the optical head and the rear bracket Jincang disc reader, said optical head at its one side or the back surface protective disc cartridge and the disc surface is placed flush with the carrier, the write head and the back surface of the one side retaining disc cassette It corresponds, for less than 5 back-sided cartridge retaining ^ les surfaces of the write head so that the optical head does not strike the back surface of single-sided guard disc box, while ensuring the normal rotary electric machine head can pass through the disc holder rotating electrical machine frame head and the top orifice plate orifice sided disc cartridge retaining a disc from the top of the rotation; one-sided since the back surface of the retaining disc cartridge needs to be placed, it is generally used for placement surface of the carrier disc, both are actually located at the same relative position on a plane, as can choose one reference surface; since the optical head and the rotary electric machine in the first embodiment are generally the same time fixed on a same lifting power unit, it can be obtained by the optical head set in power 置上的高度位置进行适当的下调降低,从而实现光头升起读写光碟时,光头的读写面能位于单面护碟盒的背面;由于光头下调降低了,所以需要增大光头的聚光镜的聚焦距离,该光头的聚光镜的聚焦距离大于单面护碟盒的背面或者光碟托架的置放面,到光碟的透光面的距离。 Height position opposing appropriate downregulation decreased, thereby realizing the optical head is raised when read DVD, the optical head can read and write on the back surface of the one side retaining disc cartridge; reduced because the optical head is reduced, it is necessary to increase the condensing lens of the optical head focusing distance, the focusing distance of the optical head is larger than one side of the condenser lens protective surface disposed disc cartridge or the back surface of the carrier disc, the distance of the translucent surface of the disc.

作为本发明第一种优选方案的进一步改进,为了避免光头读写光碟时会摩擦到单面护碟盒的背面,上述光头的读写面与单面护碟盒的背面之间保持一个防摩擦距离,从理论上来讲这个防摩擦距离越大防摩擦效果越好,但防摩擦距离越大其光头的聚焦距离必须要求更大,由于不同公司制造光头的功率会略有不同其所能达到的最大聚焦距离也就各不相同,所以该防摩擦距离必须根据实际制造情况而定, 一般可建议保持在1毫米左右。 As a further improvement of the first preferred embodiment of the present invention, in order to avoid friction when the optical head can read and write to the rear-sided DVD disc box protection, read surface of the optical head is held between the back surface of one side of a protective antifriction disc cartridge and distance from the anti-friction theory, the greater the distance the better anti-friction, anti-friction but the greater the distance from the head of its focus must demand more, due to the different companies manufacturing power head will be slightly different that can be achieved the maximum focus distance also varies, so that the anti-friction according to the actual distance has to be manufactured, the generally recommended to keep at around 1 millimeter.

作为本发明第一种优选方案的更进一步改进,上述光头的聚光镜的聚焦距离等于或大于,单面护碟盒的背面或者光碟托架的置放面,到其光碟的透光面的距离,加上一个防摩擦距离。 Still further, as a first preferred embodiment of the present invention is improved, the focusing distance of the condenser lens of said optical head is greater than or equal to, one-sided retaining disc cartridge placement or the back surface of the carrier disc, the distance of the translucent surface of its disc, plus an anti-friction distance.

由于实际制造时,光碟托架受材质选用以及与其他部件结构配合的要求等多种因素的影响,它一般都不是一个平整光滑且厚度均匀的板面,其能影响光头读碟的区域也就仅为与光头的读写面对应的区域,所以关于光碟托架厚度的取值,本发明中是指光碟托架的置放面到,光碟托架的背面且与光头的读写面对应区域面之间的距离。 Since the practical manufacture, the disc carriage is affected by many factors and material selection requirements with other parts of the structure, it is generally not a uniform thickness and smooth surface of a plate, which can also affect its reading head region read only optical head corresponding to the face area, the value of the thickness of the tray on the disc, the present invention refers to the placement surface of the disc carrier, the carrier and facing the back of the disc and the read-write head the distance between the surface areas should be. 所以使用时,当光碟托架的厚度大于,光头的读写面与单面护碟盒的背面之间保持的防摩擦距离时,光头可以直接位于光碟托架的 Therefore use, when the carriage is greater than the thickness of the disc, when the anti-friction distance, the optical head can read and write directly to the carrier disc located between the back surface of the head protection sided disc cartridge of the holding

光头读写槽中读写光碟;而当光碟托架的厚度小于,光头的读写面与单面护碟盒的背面之间保持的防摩擦距离时,光头则置于光碟托架的光头读写槽之外读写光碟;但是光碟托架本身始终都不会阻碍和摩擦到光头的读写面,所以本技术方案能将光头的聚焦距离尽可能的保持在一个最小的调控范围。 DVD read write head groove; when the thickness is less than the carrier disc, read anti-friction surface between the back surface of the head holding one side of the retaining disc from the cartridge, the disc placed on the carrier head read head DVD read write beyond the groove; carrier disc itself, but always to the reader will not hinder the friction surface and the optical head, the optical head of the present aspect can be maintained at a minimum focusing distance range of possible regulation.

再设计一种透过单面护碟盒的光头读写窗读写光碟的光碟读写设备,作为本发明第二种优选方案,以实现第二个发明目的。 Design of a read window through re-sided disc cartridge head guard disc read disc read-write device, a second preferred embodiment of the present invention, in order to achieve the second object of the invention. 该光碟读写设备除了包括光碟托架、光头、旋转电机头等传统光碟读写设备普遍具有的部件以外,该光碟托架还设有光头读写口,该光头读写口所设的位置、宽度正好使其光头的聚光镜的光束能透过该光头读写口不受阻挡,并且该光头读写口的位置、长度还与单面护碟盒的光头读写窗的位置、长度相应,从而使得光头既能透过光碟托架的光头读写口和单面护碟盒的光头读写窗读写光碟,又能使得光碟托架的水平承载强度更可靠,实际上,光碟托架的光头读写口与单面护碟盒的光头读写窗的功能完全一样,都是为了使得光头的聚光镜能透过此读写口和读写窗,然后通过对应在光碟的数据道半径上的距离来回滑动,而正常读写到光碟的全部数据,所以光碟托架的光头读写口与单面护碟盒的光头读写窗的宽度与长度参数完全可以一样,其读写口和读写窗 In addition to the optical disc apparatus comprises a CD reader carriage, an optical head, the rotary electric machine class conventional CD reader device generally have a member other than the disc reader head cradle also has a port, the port read and write head of the set position, width just so the beam condenser lens of the optical head of the optical head can be read through the unobstructed opening, and the position of the optical head to read and write ports, and also the length of one side head guard disc cartridge read window position, the respective lengths, such that the optical head to read and write both DVD disc via the optical head to read and write port and a carrier head guard sided disc cartridge read window, but the level of the disc so that the carriage bearing strength is more reliable, in fact, the disc reading head bracket write port and one side head guard disc cartridge read window function exactly the same, so that the optical head is to the condenser lens can write port and read through this window, and then through a corresponding data track on the disc radius distance fro sliding, the normal read and write all the data to the disc, the read-write head and the optical head opening disc sided bracket retaining disc cartridge read window width and length as parameters can, read and write port and a read window 宽度只要能满足适当大于或等于光头的聚光镜的直径宽度,其读写口和读写窗的长度只要能满足适当大于或等于光碟的 Long as the desired width of the diameter of the condenser lens suitable width equal to or greater than the head, the length of the read and write port and read window so long as greater than or equal to meet the appropriate disc.

数据道的半径就可满足设计需要;在套有光碟的单面护碟盒置放于光碟托架的置放面进仓后且光头读写光碟时,该光头位于其光碟托架的背面,该光头的读写面与光碟托架的背面相对应,为此该光头的读写面低于光碟托架的背面,从而使光头不会撞击到光碟托架的背面,由于本发明光碟读写设备要实现透过单面护碟盒的光头读写窗读写光碟,还包括其它更多部件的配合,如在光碟托架上设置单面护碟盒的卡盒装置或者设置光碟的释放装置,以实现光碟托架能卡住单面护碟盒在碟盒分离时不会窜动以及使得单面护碟盒能释放光碟允许碟盒分离,于是本发明对于光碟托架的水平承载强度要求必然更高,为了使得光碟托架具有更稳定的水平承载能力,所以本技术方案中的光碟托架没有在与光头对应的位置设有大跨度的光头读写槽,于是本技术方案中的光 Data track radius can meet design requirements; DVD reader when the optical head and the retaining sleeve has a single-sided DVD disc cassette is placed in the bracket placement surface Jincang disc, the disc which the optical head is located on the back of the carriage, read the back surface of the disc carrier corresponding to the optical head, for reading and writing below the back surface of the carrier disc head so that the optical head does not strike the back surface of the carrier disc, since the disc reader according to the present invention to read and write the device through the window DVD write head care sided disc cartridge, further comprising mating more other components, such as a single-sided release means is provided retaining disc cartridge means a cartridge or disc arranged on the carrier disc to achieve a single-sided disc retaining bracket can be stuck disc cartridge when the disc cartridge and separated so that one side does not traverse the cartridge releasably retaining disc DVD disc box allows the separation, so the present invention to the horizontal carrier disc bearing strength requirement necessarily higher, in order that the carrier disc has a more stable bearing capacity level, so that the carrier disc of the present aspect is not provided with a large span of the write head and the optical head at a position corresponding to the groove, so the light of the present technical solution 只能在光碟托架的下方读碟,所以该光头的读写面低于光碟托架的背面,本技术方案也可通过将光头所设置在动力装置上的高度位置实施适当的下调降低,从而实现光头升起读写光碟时,光头的读写面能到达光碟托架的背面;由于本技术方案中, 光头也下调降低了,所以同样需要增大光头的聚光镜的聚焦距离,该光头的聚光镜的聚焦距离大于,光碟托架的背面到光碟的透光面的距离,从而使光头能读写到光碟。 Only below the carrier disc Dudie, so write head is less than the back face of the carrier disc, the present technology can also be the height position of the optical head device provided on the power reduction to reduce a suitable embodiment, whereby when the optical head is raised to achieve read DVD, write head can reach the back surface of the disc carriage; Since the present aspect, the optical head is also reduced down, so the same is necessary to increase the focusing distance of the condenser lens of the optical head, the optical head condenser lens focusing distance greater than the distance to the back of the disc carriage translucent surface of the disc so that the optical head can read and write to the disc.

作为本发明第二种优选方案的进一步改进,为了避免光头读写光碟时会摩擦到光碟托架的背面,光头的读写面与光碟托架的背面之间保持一个防摩擦距离, 一般可建议保持在1毫米左右。 As a further improvement of the second preferred embodiment of the present invention, in order to avoid friction when the optical head can read and write to the rear disc CD carrier, holding a distance between the anti-friction surface and the back surface of the disc reader's optical head carriage, generally recommended maintained at about 1 mm.

作为本发明第二种优选方案的更进一步改进,光头的聚光镜的聚焦距离等于或大于,光碟托架的背面到其光碟的透光面的距离加上一个防摩擦距离。 As a second preferred embodiment of the present invention is improved still further, the focusing distance of the optical head is greater than or equal to the condenser lens, the back surface of the carrier disc to its distance from the translucent surface of the anti-friction discs plus a distance.

由于光碟读写设备中的光头部件,为了配合其他部件的工作,将在光碟读写设备中需要实施运动,为此光头的位置并不是唯一的,所以本发明对光头位置的参照和定义,以套有光碟的单面护碟盒置放于光碟托架的置放面进仓后且光头读写光碟时的状态为标准。 Since the CD reader device head member, to cooperate with other components will need to be implemented in a motion disc read-write device, the position of the head is not the only, so the reference position and the optical head is defined for this invention, in order to the optical head and the write state when the disc after the disc has a single-sided sleeve Jincang disc cartridge retaining bracket is placed in the disc surface is disposed standards.

另外, 一般光头的聚焦距离是指,光头的聚光镜(也称"物镜")聚光到达光碟透光面后而能正常读写光碟的距离,但是光头的聚光镜在光头中并不是固定的,为了适应读写不同厚度的光碟,以及适应读写光碟时振动造成的偏移等多种不利因素,光头的聚光镜一般可以在光头中较小范围的上下自动升降,所以为了有一个确定描述值,本发明中所指的光头的聚光镜的聚焦距离,是取其聚光镜与光头的读写面平齐时,光头的聚光镜聚光到达光碟透光面后而能正常读写光碟的距离,也就是光头的读写距离。 Further, generally the focusing distance of the optical head means, the head condenser lens (also called "objective") after reaching the condensing surface of the translucent disc can be read from the disc normal, but the head of the condenser lens in the optical head is not fixed in order to adapt to a variety of different thicknesses disadvantages disc reader, adapted to read and alignment during vibrations caused by the disc, the optical head condenser lens generally smaller ranges automatic lifting up and down in the optical head, it is determined to have a value described in the present condensing lens focusing distance of the optical head of the present invention referred, whichever is later read and write condensing mirror surface flush with the optical head, the optical head reaches the condensing lens converging light-transmitting surface of the disc can be read from a normal disc, the optical head is Reading distance.

由于光头聚光镜的实际聚焦距离的具体设定,不是将光头的位置实施调整后,直接测量光头到达光碟的距离并以该值为参数制造光头后就可以实现光头正常的读碟,其中还需要调控光碟读写设备的其他关联部件的配合情况才可以的。 Due to the specific set of the actual focusing distance of the condenser optical head, not to adjust the position of the head after embodiment, direct measurement of the distance the optical head and the disc reaches the parameter value is produced in the optical head can be realized after its reading head normal, which also requires regulatory of other components associated with the disc of the read-write device can. 所以最后再给出两种适用上述两种优选方案光碟读写设备的光头的制造调控方法,以实现第三个发明目的。 Finally, it is given two kinds of controlling methods suitable for producing the above-described two preferred embodiment of the optical head disc read-write device, in order to achieve the third object of the invention.

适用于第一种优选方案光头的制造调控方法: Regulation method suitable for producing a first preferred embodiment of the optical head:

第一步,将光头的高度下调降低,使其光头的读写面与单面护碟盒的背面相对应,光头的聚光镜的聚焦距离需要相应调整增大; The first step, the height of the optical head is lowered down, so that the read head surface and the back surface protection sided disc cartridge corresponds to the focusing distance of the condenser lens of the optical head needs to be adjusted accordingly increased;

第二步,调整光头的聚光镜的聚焦距离,该距离既能实现光头正常读写到光碟,还能使得光碟与单面护碟盒中间装碟部分的光碟槽的表面留有间隔距离不会摩擦, The second step, the optical head to adjust the focusing distance of the condenser lens, the optical head can not only realize the distance to the normal read-write CD, but also so that the surface single-sided DVD disc retaining groove disc cartridge loaded disc intermediate portion leaving the separation distance does not rub ,

方法之一,当光头降低的距离大于或等于单面护碟盒中间装碟部分的光碟槽的厚度时,由于光头降低的距离实际就等于光头未实施位置调整时,光头穿出光碟托架露出光碟托架的置放面的高度,单面护碟盒中间装碟部分的光碟槽的厚度只要不超过这个高度时,光碟就不会摩擦到单面护碟盒中间装碟部分的光碟槽的表面,因为光头未实施位置调整时,光头穿出光碟托架的高度面到光碟之间已经预留了有一个防摩擦距离而防止光头与光碟发生摩擦,所以这时光头的聚光镜需要增大的聚焦距离直接等于光头降低的距离加上,光头的读写面与单面护碟盒的背面之间的防摩擦距离,就能保证所制造调控制的光头能正常读写到光碟; One way to reduce the optical head when the distance is greater than or equal to the thickness of the single-sided disc retaining groove disc loaded disc cassette the intermediate portion, the optical head due to the reduced distance is equal to the actual head position adjustment is not implemented, the optical head carriage piercing the disc is exposed the height of the placement surface of the disc carrier, one surface of the intermediate retaining disc cartridge loaded disc thickness of the groove portion when the disc do not exceed this height, the disc will not rub against one surface of the intermediate retaining disc cartridge loading portion of the CD disc slot surface, because the optical head does not adjust the position of embodiment, the height of piercing the surface of the optical head of the disc carrier between the disc has been reserved from a anti-friction discs to prevent friction with the head, so when the optical head is necessary to increase the condensing mirror direct optical head focusing distance equal to the distance plus the reduction, anti-friction surface of the distance between the reader head of the back surface protective sided disc cartridge and can ensure the produced optical head can read and write transfer control to the normal DVD;

方法之二,由于上述方法之一在当光头降低的距离大于单面护碟盒中间装碟部分的光碟槽的厚度时,光头的聚光镜增大的聚焦距离采用等于光头降低的距离加上,光头的读写面与单面护碟盒的背面之间的防摩擦距离,并不是一个最优值,因为单面护碟盒中间装碟部分的光碟槽的表面,到碟片的距离过大还存在可调控的空间,所以将旋转电机头的高度降低一个值使得光碟到单面护碟盒中间装碟部分的光碟槽的表面距离适当缩小,这样可以尽可能的降低光头的聚光镜聚焦距离,从而实现降低光头的制造工艺和成本,同时也由此尽可能的 The second method, due to one of the above methods when the optical head is lowered a distance greater than the thickness of one side of the disc retaining groove intermediate disc cartridge loading portion of the disc, the optical head increases the condensing lens focus distance is equal to the optical head using a reduced distance plus the optical head anti-friction distance between the reader and the back surface of the one side retaining disc cartridge, not an optimal value, since the surface of the disc retaining groove sided disc cartridge loaded intermediate plate portion, the disc is too large to further distance presence of regulated space, so the head of the rotary electric machine such that the value of a reduced height from the surface of one side of the disc to the disc retaining disc cartridge loading portion of the disc intermediate the groove appropriately reduced, so that the optical head can be reduced as much as possible of the condensing lens focusing distance, thereby the process and reduce the manufacturing cost of the optical head, thereby also possible

降低光碟读写设备的整体厚度;该旋转电机头的降低值等于光头降低的距离减去单面护碟盒中间装碟部分的光碟槽的厚度值,且旋转电机头的降低值只能大于或等于零;于是光头的聚光镜需要增大的聚焦距离等于光头降低的距离加上防摩擦距离并再减去旋转电机头的降低值。 Reducing the overall thickness of the disc reader apparatus; reduction value is equal to the first rotary electric machine to reduce the distance minus the thickness of the optical head sided guard value intermediate disc cartridge loading portion of the CD disc slot, and the reduction value is greater than the rotary electric machine head only or It is equal to zero; then the condenser lens of the optical head is necessary to increase the distance equal to the focal distance of the optical head plus anti-friction reducing and then subtracted from the value of the rotation reduction machine head.

方法之三,而当光头降低的距离小于单面护碟盒中间装碟部分的光碟槽的厚度时,单面护碟盒中间装碟部分的光碟槽的厚度就会高过光头未实施位置调整时,光头穿出光碟托架露出光碟托架的置放面的高度,为此光碟很容易或已经摩擦到单面护碟盒中间装碟部分的光碟槽的表面,所以必须将光碟托架的高度下调降低一个值或者旋转电机头的高度上调增加一个相同值,该调整值等于单面护碟盒中间装碟部分的光碟槽的厚度减去光头降低的距离,且该调整值只能大于或等于零; The third method, when the thickness of the disc slot to reduce a distance smaller than the optical head guard sided disc cartridge loaded intermediate plate portion, the thickness of one surface of the intermediate retaining disc cartridge loading portion of the CD disc slot will not be higher than the optical head to adjust the position of the embodiments , the piercing head carriage height of the exposed disc surfaces disposed disc carrier, it is easy for this disc or a single-sided guard has a friction disc cartridge loaded intermediate portion of the disc surface of the disc slot, the disc must bracket increasing a value the same as a height value reduced to reduce the height of the head or the rotary electric machine increases, the adjustment value is equal to the thickness of the single-sided disc retaining groove disc cartridge loaded intermediate plate portion is subtracted from the optical head is reduced, and the adjustment value is greater than or only equal to zero;

如果采用降低光碟托架的高度时,光头的聚光镜需要增大的聚焦距离等于光头降低的距离加上防摩擦距离,该方法较采用增高旋转电机头的高度的方法也能尽可能的降低光头的聚光镜聚焦距离,从而实现降低光头的制造工艺和成本,同时也由此尽可能的降低光碟读写设备的整体厚度; If employed to reduce the height of the carrier disc, the optical head is necessary to increase the condensing lens focusing distance plus a distance equal to the head lowered from the anti-friction, which method uses highly increased compared to a rotary electric machine head, the optical head can be reduced as much as possible of condenser lens focus distance, thereby achieving reduced manufacturing processes and cost of the optical head, thereby also reducing the overall thickness of the disc as the read-write device;

如果采用增高旋转电机头的高度,光头的聚光镜需要增大的聚焦距离等于光头降低的距离加上防摩擦距离再加上旋转电机头的增高值,该方法较采用降低光碟托架的高度的方法,制造相对简单。 If the height of the head rotary electric machine increases, the optical head is necessary to increase the condensing lens focusing distance equal to the distance the optical head to reduce higher value plus the head of the rotary electric machine coupled with anti-friction distance, than the method using a method of reducing the height of the carrier disc , relatively simple to manufacture. 上述方法之二、三中旋转电机头的高度降低或增高的制造方法,由将旋转电机头所设置在动力装置上的高度位置进行上调或下调实现,参照调控标准以 Second, the method of manufacturing a rotary electric machine in three head height is reduced or increased, for up- or downregulated implemented by the height position of the head rotary electric machine disposed on the power unit of the above-described method, with reference to standard regulation

旋转电机头的顶碟面为准;上述方法之三中光碟托架的高度降低的制造方法, 由减少光碟托架的厚度而使光碟托架的置放面向下降低。 The top surface of the rotary electric machine head disc prevail; A method for producing a disc carrier in the height of the three methods of reduction, reduced by the reduced thickness of the disc carrier disposed facing the disc carrier.

上述方法之一、二、三中光头的聚光镜的聚焦距离的制造方法,由调控光头的聚光镜的物理厚度、直径,或者调控光头的发光源到聚光镜的距离,或者调控其光头的发光功率实现。 The method of manufacturing a focusing distance of one of the above methods, the second and third optical head of the condenser lens, the physical thickness regulated head of the condenser lens, the diameter, or modulate the optical head emitting source to the distance of the condenser lens, or the regulation of light power which the optical head is achieved.

适用于第二种优选方案光头的制造调控方法: Regulation method suitable for manufacturing a second preferred embodiment of the optical head:

由于本发明光碟读写设备的第二种优选方案相对第一种优选方案,关键不同在于,第二种优选方案光碟托架没有设置光头读写槽,光头必须完全位于光碟托架之后读碟,而第一种优选方案则设置有光碟托架的头读写槽,光头可直接位于单面护碟盒的背后读碟,所以第二种优选方案中的光头的下调降低距离较第一种优选方案中的光头的下调降低距离会多一个光碟托架的厚度值,所以将第二种优选方案中其光头降低的距离减去一个光碟托架的厚度值后,再作为 Due to the relative second preferred embodiment a first preferred embodiment of the present invention, disc read-write device, the key difference is that the second preferred embodiment is provided an optical head carriage does not read the disc slot, after its reading head carriage must be completely located in the disc, while the first preferred embodiment is provided with a read-write head of the disc carrier grooves, one side of the optical head can be positioned behind the guard disc cartridge Dudie directly, so the second preferred embodiment of the optical head down distance is preferably lower than the first after reduction scheme to reduce the distance the optical head will be one thickness value of the carrier disc, it is the second preferred embodiment in which the optical head is reduced from a value of subtracting the thickness of the carrier disc, then a

与单面护碟盒中间装碟部分的光碟槽的厚度的对比值,就能完全将第一种优选方案光头的制造调控方法应用于第二种优选方案光头的制造调控,从而获得光头的聚光镜的正确聚焦距离,从而既能实现光头能正常读写到光碟时,也能保持光碟与单面护碟盒中间装碟部分的光碟槽的表面留有间隔距离不会摩擦。 Support disc thickness sided disc cartridge loading portion of the intermediate groove on the CD ratio can be completely regulated manufacturing method of a first preferred embodiment of the optical head used in manufacture of the regulation second preferred embodiment of the optical head, the optical head condenser lens so as to obtain the correct focusing distance, thereby to achieve both the optical head when the normal read and write to the disc, but also to maintain the surface of single-sided DVD disc retaining groove disc cartridge loaded disc intermediate portion leaving the separation distance does not rub.

按照如上两种方法制造调控制的光头,就能分别适用于第一、二种优选方的案光碟读写设备中,从而实现正常读写到光碟的数据。 Produced according to the above two methods of controlling the optical head transfer, respectively, can be applied to the first, two kinds of CD case is preferably read apparatus side, enabling normal reading and writing data to the disc.

本发明的有益效果是:由于本发明的第一种优选方案光碟读写设备,建立在传统光碟读写设备的光碟托架、光碟托架的光头读写槽、光头、旋转电机头等部件基础上,仅是通过下调降低光头的高度,使得光头的读写面位于了单面护碟盒的背面,从而就能直接实现透过单面护碟盒的光头读写窗读写光碟,所以本技术方案光头的聚光镜的聚焦距离调节范围最小,整体结构改动最简单、制造所需成本最低,最易于推广。 Advantageous effect of the invention is: As a first preferred embodiment of the present invention, disc read-write device, the read-write head based on the conventional CD reader slot bracket DVD device, CD carrier, the optical head, the rotary electric machine on the basis of a top member only by reducing the height of the optical head is lowered, so that the read head is positioned backside surface of one side of the retaining disc box, so that the reader can directly read and write the disc through the optical head window guard sided disc cartridge, the present technology program focusing distance of the optical head condenser lens is adjusted to a minimum, the overall structural changes simplest, lowest cost required for manufacturing, the most easy to spread.

而本发明的第二种优选方案,虽然相对第一种优化方案还需要对光碟托架重新设计,去除了光碟托架的光头读写槽而另改设为宽度更小的光头读写口, 为此光头读写面需要调整到光碟托架的下方即背面位置,同时透过光碟托架的光头读写口和单面护碟盒的光头读写窗读写光碟,虽然更加增大了光头的聚光 While the second preferred embodiment of the present invention, although the relative the first optimization scheme also requires redesign of the disc carrier, in addition to the optical head to read and write the disc carrier and the other groove is set to change the width of the smaller read head opening, read-write head to adjust for this surface to the back surface, i.e. below the carrier disc position while the window read write head to read and write the disc through the disc cradle and the opening-sided retaining disc cartridge head, while the head is increased more condensing

镜的聚焦距离,但是却增强了光碟托架水平承载强度,适合在光碟托架上布置更多必要的其他机构或部件。 Focusing distance of the lens, but to enhance the bearing strength of the horizontal carrier disc, arranged for other mechanisms necessary or more components on the carrier disc.

最后分别适用于第一、二种优选方案的光头的制造调控方法,使得在众多需要关联考虑的设计因素中,可以简单快速正确的制造调控出所需要的光头, 并能尽可能的降低光头的聚光镜聚焦距离,从而实现降低光头的制造工艺和成本,同时也由此尽可能的降低光碟读写设备的整体厚度。 Finally, respectively, for the first manufacturing methods for adjustment of the optical head two kinds of preferred embodiment of such design numerous factors associated considerations can be easily and quickly correct manufacturing regulatory an optical head is required, and can reduce the optical head condenser lens as much as possible focusing distance, thereby achieving reduced manufacturing processes and cost of the optical head, thereby also reducing the overall thickness of the disc as the read-write device.

所以本发明为光碟无磨损保护技术的具体实现和发展作出了关键性的技术支持和贡献。 Therefore, the present invention is to make a critical contribution to the CD technology support and non-specific implementation and development of wear protection technology.

具体实施方式实施例一 DETAILED DESCRIPTION Example embodiments a

图1、 2、 3、 4所示是本发明第一种优选方案的外观示意图。 1, 2, 3, 4 is shown the appearance of the first preferred embodiment of the present invention, FIG. 本发明光碟读写设备包括光碟托架1、光头2、旋转电机头3。 DVD disc reader apparatus comprises a carriage 1 according to the present invention, the optical head 2, the rotary electric machine head 3. 光碟托架1 包括一个光头读写槽11和一个旋转电机头孔13,为了简化制造工艺,光碟托架的光头读写槽11和旋转电机头孔13连为一体,光头2与旋转电机头3设置在光碟托架1下方动力装置的滑轨14上,光头2可以沿滑轨14来回滑动,旋转电机头3则固定在滑轨14的一端,光头2与旋转电机头3可以通过光碟托架1下方的动力装置实施升降以利于配合光碟托架1实现进出仓。 Disc carriage 1 comprises a read-write head and a slot 11 hole 13 head rotary electric machine, in order to simplify the manufacturing process of the optical head reader slot, the disc carrier 11 and the rotary electric machine is integral first hole 13, the optical head 2 and the head rotary electric machine 3 disc 14 is provided on the slide rail brackets below the power plant 1, the optical head 2 may be moved back and forth along the rails 14, the rotary electric machine head 3 fixed to one end of the slide 14, the optical head 2 and the head 3 through the rotary electric machine DVD carriage below the power unit to facilitate elevating one embodiment the carrier disc 1 implemented with out of position.

本实施例中采用的单面护碟盒6,其中间装碟部分的光碟槽16的厚度为0.8 毫米。 Support sided disc cartridge employed in the present embodiment 6, wherein the portion between the loaded disc 16 is a disc slot thickness of 0.8 mm.

在套有光碟9的单面护碟盒6置放于光碟托架的置放面5进仓后且光头2 读写光碟9时,所述光头2与滑轨14的连接结构在滑轨14不做改变的情况下, 光头2下调降低1毫米,使其该光头2位于其单面护碟盒6的背面,此时光头的读写面4与单面护碟盒6的背面相对应,并低于单面护碟盒6的背面,同时还在光头的读写面4与单面护碟盒6的背面保持有0.5毫米的防摩擦距离,光头2在下调后其位置能继续使光头的聚光镜7能在读碟时,与单面护碟盒的光头读写窗8相对应。 After protecting one surface of the disc cover with a disc cartridge 9 is placed in the disc 6 disposed face of the bracket 5 and the optical head 2 binning disc reader 0900, the structure of the optical head 2 is connected with the slide rail 14 in the slide 14 without making a change, the optical head 2 reduced down one millimeter, so that the optical head 2 located on one side of the back surface protective disc cartridge 6, in which case the read head 4 and the back surface protective sided disc cartridge 6 corresponds, and lower than the back-sided retaining disc cartridge 6, the read-write head while still holding surface 4 has a distance of 0.5 mm and the rear anti-friction protective sided disc cartridge 6, the optical head 2 in its lowered position after the optical head can continue condenser lens 7 can at its reading, the optical head guard sided disc cartridge 8 corresponding read window.

在制造光头2时,由于光头2降低的距离为1毫米,大于单面护碟盒6中间装碟部分的光碟槽16的厚度0.8毫米,所以光头的聚光镜7需要增大的聚焦距离为,光头2下调降低的距离1毫米,加上防摩擦距离0.5毫米,等于1.5毫米。 In the manufacture of the optical head 2, the optical head 2 due to the reduced distance is 1 millimeter, greater than one surface of the intermediate retaining disc cartridge 6 loaded DVD disc portion 16 of the grooves 0.8 mm thickness, the head of the condensing lens 7 needs to increase the focusing distance of the optical head 2 lowered down distance of 1 mm from the anti-friction plus 0.5 mm, equal to 1.5 mm.

光头的聚光镜7聚焦距离增大的具体制造,该工艺可以由调整光头的聚光镜7的物理厚度或直径实现。 The condensing lens focusing the optical head 7 increases from a specific manufacturing process of the optical head can be realized by adjusting the physical thickness or diameter of the condenser lens 7.

使用时,光头2则直接到达单面护碟盒6的背面,透过单面护碟盒的光头读写窗8正常读写到光碟9的数据。 In use, the optical head 2 directly to the back surface of the one side retaining disc cartridge 6, read and write data to the read window 8 normal disc 9 through the head guard sided disc cartridge.

实施例二 Second Embodiment

与实施例一相同之处不再赘述,不同之处主要在于本实施例采用了适用于第一种优选方案光头的制造调控方法之二:为了尽可能的降低光头的聚光镜7的聚焦距离,从而实现降低光头2的制造工艺和成本,同时也由此尽可能的降低光碟读写设备的整体厚度。 An embodiment in common with the embodiment will not be repeated, except that the primary regulation according to the present embodiment employs the method for manufacturing a first preferred embodiment is suitable for optical head II: In order to minimize the optical head 7 of the condenser lens focusing distance, thereby process and reduce the manufacturing cost of the optical head 2, thus also possible to reduce the overall thickness of the disc reader apparatus.

所以还可将旋转电机头3的高度降低一个值,旋转电机头3的降低值等于, 光头2降低的距离1毫米,减去单面护碟盒6中间装碟部分的光碟槽16的厚度0.8毫米,所得值为0.2毫米,该值大于O为可取值,所以旋转电机头3与滑轨14的连接结构在滑轨14不做改变的情况下,旋转电机头3下调降低0.2毫米, 下调降低时以参照电机头的顶碟面17的变动为准。 Therefore, also the height of the rotary electric machine head 3 decreases a value, reducing the value of the first rotary electric machine is equal to 3, the optical head 2 a reduced distance of 1 mm sided subtracting intermediate retaining disc cartridge 6 loaded DVD disc portion 16 of the groove a thickness of 0.8 mm, the resulting value is 0.2 mm, which is greater than the value to be O, so that the rotary head 3 and the motor 14 connected to the slide rail structure in the case where the rail 14 is not changed, the rotary electric machine head 3 lowered down 0.2 mm, down Referring first to the motor 17 changes in a top surface of the disc decreases prevail.

于是光头的聚光镜7需要增大的聚焦距离为,光头2降低的距离1毫米,加上防摩擦距离0.5毫米,再减去旋转电机头3的降低值0.2毫米,等于1.3毫米。 Thus the condenser lens 7 of the optical head is necessary to increase the focusing distance of the optical head 2 a reduced distance of 1 mm and 0.5 mm from the anti-friction plus, minus the value of the rotary electric machine 3 of the head is lowered 0.2 mm, equal to 1.3 mm.

实施例三 Third Embodiment

与实施例一相同之处不再赘述,不同之处主要在于本实施例采用了适用于第一种优选方案光头的制造调控方法之三中的一种: An embodiment in common with the embodiment will not be repeated, except that the present embodiment employs the main three regulation of one of the suitable method for manufacturing a first preferred embodiment of the optical head:

本实施例中采用的单面护碟盒6,其中间装碟部分的光碟槽16的厚度为1.2 毫米。 Support sided disc cartridge employed in the present embodiment 6, wherein the portion between the loaded disc is the disc slot 16 of 1.2 mm thickness.

在制造光头2时,由于光头2下调降低的距离为1毫米,小于单面护碟盒6 中间装碟部分的光碟槽16的厚度1.2毫米; In the manufacture of the optical head 2, since the optical head 2 is lowered to reduce the distance of 1 mm, less than one side of the intermediate retaining disc cartridge 6 loaded DVD disc portion 16 of the groove a thickness of 1.2 mm;

所以首先增高旋转电机头3的高度值,旋转电机头3的增高值等于,单面护碟盒6中间装碟部分的光碟槽16的厚度1.2毫米,减去光头2下调降低的距离l毫米,所得值为0.2毫米,该值大于O为可取值,所以旋转电机头3与滑轨14 的连接结构在滑轨14不做改变的情况下,旋转电机头3上调增高0.2毫米,上调增高时以参照电机头的顶碟面17的变动为准。 So, the first rotary electric machine head height value increased to 3, the rotary electric machine is equal to the first higher value is 3, one surface of the intermediate retaining disc cartridge 6 loaded DVD disc groove portion 16 of a thickness of 1.2 mm, by subtracting the optical head 2 is reduced to reduce the distance l mm, when the resulting value is 0.2 mm, which is greater than the value to be O, so that the structure of the rotary electric machine 3 is connected to the head rail 14 in a case where the rail 14 is not changed, the first rotary electric machine 3 increased up 0.2 mm, increased upregulation Referring first to the motor 17 changes in a top surface of the disc prevail. 于是光头的聚光镜7需要增大的聚焦距离为,光头2下调降低的距离1毫米, 加上防摩擦距离0.5毫米,再加上旋转电机头3的增高值0.2毫米,等于1.7毫米。 Thus the condenser lens 7 of the optical head is necessary to increase the focusing distance of the optical head 2 is lowered down distance of 1 mm from 0.5 mm plus the anti-friction, coupled with the rotary electric machine head 3 increases the value of 0.2 mm, equal to 1.7 mm.

实施例四 Fourth Embodiment

与实施例一相同之处不再赘述,不同之处主要在于本实施例采用了适用于第一种优选方案光头的制造调控方法之三中的另一种: An embodiment in common with the embodiment will not be repeated, except that the present embodiment is mainly adopted in another three regulation applicable to the method for manufacturing a first preferred embodiment of the optical head:

本实施例中采用的单面护碟盒6,其中间装碟部分的光碟槽16的厚度为1.1 毫米。 Support sided disc cartridge employed in the present embodiment 6, wherein the portion between the loaded disc 16 is a disc slot thickness of 1.1 mm.

在制造光头2时,由于光头2下调降低的距离为1毫米,小于单面护碟盒6 中间装i莱部分的光碟槽16的厚度1.1毫米; In the manufacture of the optical head 2, since the optical head 2 is lowered to reduce the distance of 1 mm, less than one side of the intermediate retaining disc cartridge 6 loaded DVD i les groove portion 16 of a thickness of 1.1 mm;

所以首先降低光碟托架的置放面4的高度值,光碟托架的置放面4的降低值等于,单面护碟盒6中间装碟部分的光碟槽16的厚度1.1毫米,减去光头2下调降低的距离1毫米,所得值为0.1毫米,该值大于O为可取值,所以其光碟托架1的背面位置高度不做调整,即光碟托架1与光碟读写设备的连接结构不做任何改变,由减少光碟托架1的厚度Ol毫米而使光碟托架1的置放面4向下降低0.1毫米,所述光碟托架1的厚度,是指光碟托架1的置放面5到,光碟托架1 的背面且与光头2的读写面4对应区域面之间的距离。 So, the first surface of the disc placed reduced height value of the carrier 4, reducing the value of the carrier disc placement surface 4 is equal to the thickness of one surface of the intermediate retaining disc cartridge 6 loaded disc portion groove 16 1.1 mm disc, the optical head is subtracted 2 reduced from 1 mm down, the resulting value is 0.1 mm, which is greater than the value to be O, so that the position of a back surface of the carrier disc height no adjustment, i.e. the carrier disc 1 and the connecting structure of the CD read-write device without any change by reducing the thickness of the disc carriage 1 mm Ol CD the carrier surface 1 is placed 4 lowered down 0.1 mm, the thickness of the carrier disc 1, the disc carriage means is disposed 1 5 to the face, the back of the carrier disc 1 and the optical head 2 and the face 4 of the reader corresponds to a distance between the surface region.

于是光头的聚光镜7需要增大的聚焦距离为,光头2下调降低的距离1毫米, 加上防摩擦距离0.5毫米,等于1.5毫米。 Thus the condenser lens 7 of the optical head is necessary to increase the focusing distance of the optical head 2 is lowered down distance of 1 mm from the anti-friction plus 0.5 mm, equal to 1.5 mm.

实施例五 Fifth Embodiment

图5、 6所示是本发明第二种优选方案的外观示意图。 5, FIG. 6 is an external second preferred embodiment of the present invention, FIG. 本发明光碟读写设备包括光碟托架1、光头2、旋转电机头3。 DVD disc reader apparatus comprises a carriage 1 according to the present invention, the optical head 2, the rotary electric machine head 3. 光碟托架1 包括一个光头读写口12和一个旋转电机头孔13,该光头读写口12所设的位置与光头的聚光镜7的位置相对应,宽度大于或等于光头的聚光镜7的直径,约为6〜10毫米左右,长度大于或大于光*莱9的数据道半径,约为39〜41毫米左右, 从而使得光头2的光束能通过在该光头读写口12中来回移动后,正常读写到光碟9的全部数据。 Disc carriage 1 comprises a read-write head and a rotating electric machine port 12 first hole 13, the head position of the write port 12 is provided with a position of the optical head corresponding to the condenser lens 7, a width greater than or equal to the diameter of the condenser lens 7 of the optical head, after about about 6~10 mm, length greater than or greater than the radius of the optical data tracks 9 * Levin, about about 39~41 mm, so that the light beam by the optical head 2 is moved back and forth in the optical head 12 to read and write port, normal all read and write data to the disc 9.

光头2与旋转电机头3设置在光碟托架1下方动力装置的滑轨14上,光头2可以沿滑轨14来回滑动,旋转电机头3则固定在滑轨14的一端,光头2与旋转电机头3可以通过光碟托架1下方的动力装置实施升降以利于配合光碟托架1 实现进出仓。 The optical head 2 is provided with the rotary electric machine head 3 on the disc carriage 14 below the rail 1 power unit, the optical head 2 can slide back and forth along the rail 14, the rotary electric machine head 3 fixed to one end of the slide 14, the optical head 2 and the rotary electric machine head 3 may be below the power unit with the disc carrier to facilitate lifting embodiment 1 achieved by the disc cartridge out of the carriage.

本实施例中采用的单面护碟盒6,其中间装碟部分的光碟槽16的厚度为0.8 毫米。 Support sided disc cartridge employed in the present embodiment 6, wherein the portion between the loaded disc 16 is a disc slot thickness of 0.8 mm.

在套有光碟9的单面护碟盒6置放于光碟托架的置放面5进仓后且光头2 读写光碟9时,所述光头2与滑轨14的连接结构在滑轨14不做改变的情况下, 光头2下调降低2毫米,使其该光头2位于其光碟托架的光头读写口12的背面, 此时光头的读写面4与光碟托架的光头读写口12的背面相对应,并低于光碟托架的光头读写口12的背面,同时还在光头的读写面4与光碟^^架的光头读写口12的背面保持有0.5毫米的防摩擦距离,光头2在下调后其位置能继续使光头的聚光镜7能在读碟时,与光碟托架的光头读写口12以及单面护碟盒的光头读写窗8相对应。 After protecting one surface of the disc cover with a disc cartridge 9 is placed in the disc 6 disposed face of the bracket 5 and the optical head 2 binning disc reader 0900, the structure of the optical head 2 is connected with the slide rail 14 in the slide 14 without making a change, the optical head 2 reduced down two millimeters, so that the optical head 2 is in its back surface of the optical head disc carrier reader port 12, then the read surface of the optical head 4 and the head carrier to read and write port CD 12 corresponding to the back surface, and below the carrier disc read-write head rear surface of the opening 12, while also the optical head 4 to read and write the back surface of the head opening 12 of the reader holder holding the disc ^^ 0.5 mm antifriction distance, the optical head 2 in the lowered position of the optical head can continue condenser lens 7 can at its reading, the optical head and the disc carrier 12 and the write port single-sided disc cartridge head guard 8 corresponding read window.

本实施例中,光碟托架l的厚度为l毫米。 In this embodiment, the thickness of the carrier disc l is l mm. 在制造光头2时,由于光头2下调降低的距离为2毫米减去光碟托架1的厚度1毫米,其结果值为1毫米而大于单面护碟盒6中间装碟部分的光碟槽16的厚度0.8毫米,所以光头的聚光镜7需要增大的聚焦距离为,光头2下调降低的距离2毫米,加上防摩擦距离0.5毫米,等于2.5毫米。 In the manufacture of the optical head 2, since the carriage 2 mm 1 mm thick discs by subtracting an optical head 2 is reduced to reduce the distance, the result is greater than 1 mm in one side of the intermediate retaining disc cartridge 6 loaded DVD disc portion 16 of the groove 0.8 mm thickness, the head of the condenser lens 7 is necessary to increase the focusing distance, the optical head 2 is lowered to reduce the distance of 2 mm from the anti-friction plus 0.5 mm, equal to 2.5 mm.

使用时,光头2则到达光碟托架的光头读写口12的背面,此时光头读写口12的位置分别与光头的聚光镜7和单面护碟盒的光头读写窗8的位置相对应并位于两者之间,于是光头2通过透过光碟托架的光头读写口12后,再透过单面护碟盒的光头读写窗8而正常读写到光碟9的数据。 Position of use, the back surface of the optical head 2 to read and write head of the disc carrier port 12 is reached, this time the position of the optical head 12 to read and write ports, respectively condenser lens 7 and the optical head guard sided disc read-write head cartridge corresponding to the window 8 and between the two, then the optical head 2 through the disc cradle through the rear opening 12 of the optical head read, write and then read and write to the window 8 and the normal data disc 9 through the head guard sided disc cartridge.

当然在本实施例中,为了简化制造工艺,光碟托架的光头读写口12与旋转电机头孔13也可连为一体制造。 Of course, in the present embodiment, in order to simplify the manufacturing process, the carrier disc 12 of the optical head and the write port hole 13 head rotary electric machine may be manufactured as a single entity.
