Description
Technical field
The present invention is relevant a kind of CD-RW discsCD-RW, refers to a kind of two-sided DVD CD-RW discsCD-RW especially.
Background technology
DVD (Digital Versatile Disc) is for just there being the new digital light storage medium formats of preliminary unification specification at the bottom of nineteen ninety-five.The same with present VCD photo CD, can stored images, sound, general data.Different application just derives different forms, as DVD-ROM, DVD-RAM, DVD-R, DVD-ViDeo etc.
The DVD place different with VCD except since the progress of photoelectric technology make storage time by became 2 hours in 74 minutes (single-surface single-layer video disc structure) above, the compress mode of image also advances to be raised to MPEG2 from MPEG1, and the resolution of DVD stored picture also is the highest in the present commercial media.
From being written into the viewpoint of pattern, the pattern that is written into of existing DVD laser disc data can be divided into these two kinds of prerecorded and recordable types, and with the utilization of a slice laser disc, its selectivity is quite limited.For example, the laser disc person who belongs to prerecorded at present just can't write record to it; The laser disc person who belongs to recordable type then only is made for the usefulness of recording medium and since the laser disc of recordable type may be in the pipeline of commodity by manifolding, therefore and be not suitable for use in the business software laser disc cover, destroy or deliberately be written into virus.In addition, do not worry and in transport pathway, to be rewritten though the prerecorded laser disc can be suitable as the storage of business software, but also owing to can't write new data, so its execution result certainly will must be stored in the different CD-RW discsCD-RW in addition, but so will be easier to cause scattering or losing of data.
Various industrial standards have appearred in so-called prerecorded DVD laser disc at present, and more general comprises: main specifications such as DVD-5, DVD-9, DVD-10 and DVD-18; Wherein DVD-5 is the structure of single-surface single-layer, and capacity is 4.7GB; DVD-9 is the structure of single-surface double-layer in addition, and total volume is 8.5GB; And DVD-10 is two-sided single layer structure, and its total volume can reach 9.4GB; And DVD-18 is two-sided double-decker, and its total volume can be up to 17GB.The difference of above-mentioned each specification capacity and structure, detailed listed as table one:
The specification capacity of table one, present DVD laser disc and structure compare:
| Single-surface single-layer | Single-surface double-layer | Two-sided individual layer | Two-sided bilayer | |
| ????DVD-5 | ????4.7GB | |||
| ????DVD-9 | ????8.5GB | |||
| ????DVD-10 | ????9.4GB | |||
| ????DVD-18 | ????17GB |
Can summarize from table one: at present known DVD laser disc structure can be divided into single face and two-sided two kinds; Wherein the laser disc capacity of bilateral structure is double in the capacity of single face; And single compared from individual layer and double-deck two kinds of structures, contain double-deck DVD laser disc capacity again greater than the capacity of individual layer laser disc.
The making conception of two-sided laser disc, the summary of the invention in the 4th, 310, No. 919 patents of the U.S. discloses to some extent, and this patent is that video-audio signal is pre-recorded in the two sides of same CD-RW discsCD-RW, so as to increasing the laser disc capacity of CD-RW discsCD-RW.And about the concrete making step of two-sided laser disc, then be exposed in the summary of the invention of the 5th, 540, No. 966 patents of the U.S., it is to be binded by the structural sheet of two different recording formats (structural sheet that respectively contains the laser disc content of pre-recording) to form, and makes the two-sided laser disc content that preload all can be provided of a laser disc whereby.
The U.S. the 6th, 205, No. 112 patents (hereinafter to be referred as ' 112 patent) then propose the structure of another two-sided laser disc: be on the two sides of a two-sided laser disc, make the CD form that wherein simultaneously can read for traditional CD-ROM device, another side is then made the form that has only present DVD CD-ROM device just to can read.What be somebody's turn to do the primary solution of ' 112 patent is audio/video media dealer's problem, and make with in a slice laser disc, the medium that traditional laser disc function of can pre-recording reads, can pre-record the again DVD optical disc media of high power capacity, so just, can be in the middle of with a slice laser disc preload simultaneously: media contents such as film, recreation, music, deal with new, the old consumer demand that differs of present laser disc fetch equipment.
Though ' 112 patent has disclosed the two-sided laser disc structure that a kind of two sides form differs from one another, should be noted that: the two sides of this kind laser disc structure all is the laser disc structure of prerecorded, therefore fails to break through existing limitation on using.Similar patent is found in again that Announcement Number is No. 98/38637 international application of WO, and this international application discloses a kind of two sides and constitutes by the semi-manufacture of prerecorded medium.
