Description
Technical field
The present invention particularly utilizes the manufacture method of the outer ring application of force with the media for storing optical information of separation template and wall about one about a kind of manufacture method of media for storing optical information.
Background technology
Along with information and multimedia arriving from generation to generation, electronic product also constantly increases for the storage density of Storage Media and the demand of capacity.Traditional Storage Media roughly can be divided into two classes, is respectively magnetic recording type medium and optical recording type medium.Preponderate with optical recording type medium in the market, it comprises CD-ROM (CD-ROM), writable disposable type CD (CD-R), rewritable type CD (CD-RW), read-only type Video CD (DVD-ROM), writable disposable type Video CD (DVD-R, DVD+R), rewritable type Video CD (DVD-RW, DVD+RW) and dynamic random memory Video CD (DVD-RAM) or the like.
In the face of more and more huger audio and video information amount, improve the volume of information of CD, be the target that industrial community is pursued always.And therefore DVD has occupied certain ratio because have the information storage capacity bigger than CD on light memory medium market.Present DVD has and sees pattern outside the difference, from single-surface single-layer (Single side single layer), single-surface double-layer (single sidedual layer), two-sided individual layer (Dual side single layer), two-sided bilayer (Dual side duallayer), their storage volume scope does not wait from 4.7GB to 17GB yet.
Another side is blank (Dummy) if having only single face to store data, and then its storage volume is about 4.7GB, is the read-only type Video CD of single-surface single-layer, is called DVD-5 again; If on the disc of single face, store double-deck capacity, because deduct space that bonding accounts for and the instruction that connects two-layer data, the capacity that the historical facts or anecdotes border can store has lacked some than the twice of single-surface single-layer capacity, be the read-only type Video CD of single-surface double-layer, claim DVD-9 again, its storage volume is about 8.5GB.If in conjunction with the technology of two-sided bilayer, then storage volume can increase and be 13.2GB, that is DVD-14 (single-surface single-layer adds single-surface double-layer), or the storage volume amplification is 17GB, that is DVD-18 (two-sided bilayer).Wherein, acceptance is higher on DVD discs market, for single-surface single-layer DVD-5 and two kinds of discs of single-surface double-layer DVD-9, because the disc of these two kinds of specifications has all saved by access the time " turn-over " trouble, so comparatively the consumer likes.
Single-surface double-layer DVD-R with 8.5GB capacity because capacity is big, adds the structure of writable disposable, also more and more is subjected to market and payes attention to.As shown in Figure 1, known single-surface double-layer DVD-R disc 10, contain one first substrate 11, one first record lamination (first recordingstack, L0) 12, one wall 13, one second record lamination (second recording stack, L1) 14, and one second substrate 15.Wherein, the first record lamination 12 and the second record lamination 14 are coated on respectively on the data face of first substrate 11 and second substrate 15, and wall 13 is interposed between the first record lamination 12 and the second record lamination 14.
In the known technology, for single-surface double-layer DVD-R disc 10, the photopolymerization processing procedure, being called for short 2P processing procedure (Photo-Polymerization Process) be one of manufacture method commonly used, below just does a simply introduction at the 2P processing procedure:
Please refer to Fig. 2 A～2F, it has on first substrate 11 of pre-rail groove at quarter (pre-grooved) in one, forms the first record lamination 12, and light binding 13 ' in regular turn.Then, have the template (master) 16 of prerecording ditch groove with one, be pressed on the light binding 13 ', and,, form wall 13 to solidify colloid via UV-irradiation.After divesting template 16, on interlayer 13 between the formation groove, form the second record lamination 14 again.At last, behind second substrate, 15 coatings, one joint glue 17 ', engage, after solidifying processing, form a knitting layer 17 again, promptly finish the making of single-surface double-layer DVD-R disc 10 with the second record lamination 14.
From the above, when template 16 divests,, need apply stronger pulling force wall 13 is separated with template 16 because the adhesion between template 16 and the wall 13 is strong.Yet, on the adhesion of first record lamination 12 and wall 13 is relative a little less than, can't bear powerful pulling force.Therefore, when divesting the step of template 16, then easily 13 fragmentation of origination interval layer are peeled off (shown in Fig. 2 D dotted line) or are caused first to write down the phenomenon that lamination 12 separates with first substrate 11, and influence the travel path of laser access, and then cause the yield of disc on the low side, increased production cost.
Recently, the dealer is developed again and a kind of inner ring application of force that is used in disc, so that the method that template is separated with wall, yet, but less because of the area of the disc inner ring application of force, also can't effectively solve the too strong problem of clinging power between template and the wall.
Therefore, when how to solve known single-surface double-layer DVD-R disc and divesting template, the too strong problem of the clinging power of template and wall, and then solve problems such as the disc process rate is on the low side, one of important topic of the real manufacture method that belongs to current media for storing optical information.
Summary of the invention
Because above-mentioned problem, purpose of the present invention causes wall fragmentation because of the clinging power between template and wall results in too by force when divesting template for a kind of avoiding is provided, or the manufacture method of the media for storing optical information of the first record lamination phenomenon of separating with first substrate.
For reaching above-mentioned purpose, the manufacture method of complying with media for storing optical information of the present invention comprises following steps:
Form one first record lamination on one first substrate;
Form a wall on this first record lamination;
With template and this wall pressing of a diameter, make the periphery of this template expose to this first substrate greater than this first substrate;
Exposed parts in this template imposes at least one external force, so that this template is separated with this wall;
Form one second record lamination on this wall; And
One second substrate is engaged with this second record lamination.
The present invention forms a media for storing optical information according to above-mentioned steps.
From the above, because of manufacture method according to media for storing optical information of the present invention, utilize the mode of the outer ring application of force that template is separated with wall, therefore, can avoid causing the wall fragmentation when divesting template because of the clinging power between template and wall results in too by force, or the first record lamination phenomenon of separating with first substrate, to solve problems such as the disc process rate is on the low side.
The present invention also comprises other technical characterictic, elaborates below with reference to the drawings and specific embodiments.
