Description
Technical field
The present invention prints about CD label, especially, is used for optical disk image recording system and the method for an image recording on the label layer (Label layer) of CD about a kind of.
Background technology
Along with recordable CD (Recordable optical disc) and can rewrite formula CD (Rewritable optical disc) and be used to storage data widely, subsequently and the problem of coming promptly is how to manage at the CD of storage data.
Along with the consumer expects to have mode more easily, discern them and write the data of recording on the extremely own CD that is had, the method that reaches mark (Labeling) with for example literal (Text) and image forms such as (Figure) on the non-data side of these a plurality of CDs develops constantly.The basic skills of mark CD with a nonvolatil mark device (Marker) (for example comprises, sharp-pointed pen at quarter (Sharpie marker)) writes at CD entity and write on the non-data side of record, or print and paste formula label paper (Papersticker label) and it is attached on the non-data side of CD.Other comprise inkjet printing (Ink jet), thermal wax transfer (Thermal waxtransfer) and thermal dye transfer (Thermal dye transfer) at the entity mask method of carrying out in the conventional optical disc player ... etc. method.
One subject matter of robotization mark CD, be on label surface (Label surface) (just so-called non-data side or label layer), do not have the mark (Marking) of track (Track) or other patterns to assist to determine radial location, make that the label layer on CD marks and is not easy.Compared to the situation of label layer, existing data Layer (Data layer) on various CD carries out the common pre-groove (Pregroove) that forms that forms earlier of strategy that data are write record on this CD.On this groove, be marked with presumptive address sign indicating number (Predetermined address codes), absolute time code (AbsoluteTime In Pregroove codes for example, ATIP codes), follow the foundation of rail in order to offer optical information recorder/transcriber (Optical information recording/reproducing apparatus) (for example video disc recording machine), and then assist recording/reading data.Basically, above-mentioned presumptive address sign indicating number is represented with time value.Letter speech ground says that when CD player was instructed to carry out reading and writing data, absolute time code was read to be positioned an ad-hoc location, and this mechanism has been simplified the process of the optical disc data layer being carried out addressing.
Also have a technology about drawing image on the CD label face to be suggested in recent years, as U.S. Patent number the 6th, 864, No. 907 disclosed, and the content of this technology provides one to react and change the label layer of color at light or heat on CD.This label layer is configured in the face of an optical access head, and a laser beam is transmitted on this label layer, makes this label layer change color to form image, and the image that forms on this label layer can be for identification optical disc data content.One group of alignment mark (Alignment mark) is pre-formed on this label layer to help the location with printed image.Before on the label layer, CD must overturn in advance in print image.
U.S. Patent number the 5th, 565, No. 668 open one scan systems, this scanning system comprises the multi-focus lens (Multi-focal lens) 12 of a single lens member, as shown in Figure 1, this single lens member is made of scope face portion 12b with one first focal length and outside annular minute surface part 12a with one second focal length.This scanning system thereby can set up the focus point position (being A1 and A2) of two separation by single light source 10.In addition, a plurality of lens components also can be separated the configuration use.Fig. 2 has represented another multi-focus lens system, and it is one to comprise the multi-focus lens 14 of the lens component of two separation, that is a back lens member 14a and a front lens member 14b.Therefore be focused focus B1 and B2 from the light of light source 10 in two separation.Not by the light of front lens member 14b, be focused focus B2 by back lens member 14a as shown in the figure in far-end.And the light by back lens member 14a and front lens member 14b is focused as shown in the figure in focus B1 nearby simultaneously.The optical characteristics of looking closely front lens member 14b, the position of focus B1 also can be to be positioned at apart from lens 14 at a distance.
Therefore, a fundamental purpose of the present invention is promptly in that a kind of optical disk image recording system and method are provided, in order to data such as image are recorded on the label layer of CD.In addition, be optical disk image recording system and the method for presumptive address sign indicating number of utilizing on the optical disc data layer according to optical disk image recording system of the present invention and method on this label layer, to position.Especially, a multi-focus lens module is utilized to a laser is focused on respectively on optical disc data layer and the label layer, will finish in a step with print image in location on the CD with this.
