INSTRUCTION DESCRIPTION (1) The present invention relates to a small-sized optical storage disk for a light storage disk, a light coating. In particular, it relates to a data carrying layer that is usually formed with a multi-layer optical data storage medium. Because it is recorded by the illumination data carrying layer through the substrate, it is located in the classification of the substrate attached media. More illumination light is retrieved on the surface of the data carrying layer. The optical data storage medium or the magnetic disk read optical data storage medium or write-once is embodied. The read-only optical data is stored as a series of physical marks or bumps. It is formed using an injection molding process. A bump cannot be erased or repeatedly written. Diffraction characteristics when compared to the area of the read-only data bearing layer. The difference in the storage characteristics of the read-only optical data is achieved. A type of polycarbonate substrate that is written once to the optical data storage medium. The data is used to modulate the beam to illuminate the organic dyes. The selected regions of the organic dyes that are not affected by the high-density organic dyes are chemically compatible, that is, the regions with lower light reflectivity are stored. The data is recorded as One of the dark regions of the sequence with low reflectivity is formed in the data retrieval, especially before the first different optical resources media, such as the real and the lack of physical records in the disk carrier layer, so this is used first. Through-characteristics, material storage, and physical mark formation, the physical mark or the data in the polycarbonate test is the substrate on which the components usually read the data. And can be recorded as the media of the media, or the block usually has a different physical symbol or number or a block of bumps with different tethers, which are recorded by the density of the organic material system. The layers are recorded across the substrate. When the domain ratio is compared, the change of high-density light is accepted and the "dark" region is generated, and the difference between the & optical rate of the high reflectivity space is achieved.

Although it is not suitable for the electric material, the dielectric layer is formed from the nitrogen layer, and the first metal gold is formed. The layer is placed between the substrate and the first dielectric layer. The two layers are formed to cover the continuity and optical constants of the read-only and writable components. The wavelength of the material is adjusted. The thickness of the layer f. In the embodiment, the ruthenium oxynitride layer has significant advantages, for example; the shovel is achieved by sputtering a ruthenium through a mixture of oxygen and nitrogen. The ruthenium oxynitride layer is changed by oxygen. The ratio of nitrogen to nitrogen is adjusted and controlled by its optical index. Fine tuning of the j-sense can lead to a high degree of spectral modulation to achieve accurate optical enthalpy. The parameters that can be controlled and changed are controlled by the intrinsic indicators controlled by the mixture of oxygen and nitrogen. And thickness control. The optical modulation of the enamel layer produces a moderate surface reflection coefficient for tracking and aggregation while still maintaining sufficient laser absorption for writing capability. It does not require any single continuous layer structure that is shielded on the disk and is applied to the entire surface at the same time. The coating is continuous and does not change depending on the degree of pre-recording or writability of the disk. ^例十'A disc has a spiral pattern of bumps and/or a spiral domain surface, the outer diameter of the disk is not more than 50 mm, and is usually 32 mm or less, and the thickness is usually 〇6 mm.

The application is provided, and the summary of the person's summary is M-1 1 628. The title of the US patent application is unknown. The title is ''Use the female die. Molded discs "t, all of which are incorporated by reference. The female die has recesses and grooves corresponding to the original laser cut. Resin and ruthenium: flow into these depressions and grooves' as formed by injection molding to form the bumps and domains of the disc. When the disk is formed using the parent stamper, it is more difficult for the resin to completely flow into the small recess to flow on the small bump (forming the small recess). Therefore, the small size of the bumps (discussed in detail below) limits the size of the user's disc to about 50 mm or less 'and preferably 32 angstroms to Κ 〇 填 填 填 填 填 , , , , In the meantime, the ability of the tree to fill up the sub-quantity also reduces the very high and short mold resin. The minimum size of the mold is limited to the desired resin from which it is usually to be two kinds of squares; First. This can be attributed to the limitation of the viscous center of the grease due to the small depression towards the disk. The method of molding the bumps makes the resin, the low molecular disk use temperature: injection molding, so any three methods limit the diversity of the mold. This requires the resin to be as low as possible. The outer edge flows, so the optimum degree of the diameter of the disk is the minimum degree of viscosity. The amount of viscosity β will damage the maximum value of the disk t. In addition, the treatment has generally been used to increase the resin during the process of the recess process. The resin is completely filled with air and the heat is completely recessed. Because the injection molding period is filled along the outer edge, the smaller the depression, the easier it is to reach the method. In order to use low-score physical integrity, and the method is to heat the resin to the maximum temperature to obtain the ability to cause scorching, the cooling of the resin must flow outward in time.

Description of invention (8) Distance is reached. The current injection molding process is a diaphragm having an outer diameter of about 50 mm; ^ 疋 maximum distance result is less than one mm of straight: where; and == diameter causes the disc to have practically small storage capacity . Straight: The amount of resin to be injected is minimized ("injection" size is injected into ^ = the amount of resin used) to maximize the injection speed, which also helps to minimize the viscosity coefficient of the fat. This is due to the larger resin: in the case of larger cooling and smaller viscosity coefficient, "generate inflow = J: more difficult time. The less time to inject the resin, the more it stays in: and the process produces The less the cooling, the lesser the thickness of the polycarbonate is found to be between 5 grams and 0.8 grams, which results in a disc thickness of about 6 mm or less and a general thickness of 0.6 mm ± 〇. 3 mm. A smaller amount will result in a disc that is too thin and unstable, while a higher amount will result in an injection size that is difficult to maintain at the desired temperature. A higher amount also produces a thicker disc (unexpected from a product point of view) or requires a disc The outer diameter is increased, which deteriorates the flow problem described above.

The thickness of the phase change layer and the dielectric layer can vary depending on the desired wavelength of the read and write laser. The phase change layer and the "electric layer/child product details and the respective materials and characteristics are described in U.S. Patent Application Serial Nos. 9/764, 〇42 and 〇9/854,333. According to the invention, the data is written to the domain surface 丨i 〇 of the first surface optical disc instead of the recess 112. The first surface optical disc is a read or write laser impact and is reflected on the first surface (e.g., light coating 212), rather than a disc that passes through the substrate before impacting the information or data layer. When it is written in the groove, when it is written on the domain surface, the optical phase change will produce an effective shallow groove. This produces a higher contrast between the write and non-write parts. Therefore, the % system receives a higher reflected signal amplitude, thereby improving the performance of the system. Additional details of the grating structure and phase change material utility are disclosed in the US Μ 1 1 628 filed on the 24th of the year. The total number of US patent applications is unknown. The title is "For the mother pressure of the disc molding The use of the model, and, on February 26, 2002, the application of the United States Dijon 12013, unknown 'titled' " double-density CD with relevant characteristics, ", its ^ is incorporated into the reference. It should be noted that although the description relates to the early lean layer on the side of the optical disc, the two data layers on one side are also suitable, as disclosed in co-pending U.S. Patent Application Serial No. 09/764, 042.

INSTRUCTIONS (10) 112a-b, although their widths can be different, are shown to have the same width. The grooves 112a-b are grooved, have inclined left and right walls 2〇2 and a flat bottom 204, and can be placed in a rotating pattern or another desired pattern. The left and right side walls 202 are typically angled a (alpha) from about 3 degrees to about 50 degrees, with a typical angle of about 45 degrees. This angle is relative to the bottom of the groove 112 where the optical disk is not applied, and is measured along the groove wall between 〇.lTh and 〇.9Th, where Th is the height of the groove. This range should be 45 degrees nominal + 15 degrees. A third graph shows a graphical representation of the relationship between angle a versus push-pull signal rate and process output. A push-pull signal is herein defined as a measurement of an electronic signal that is priced by a separate detector component in an optical head that traces the erroneous signal. When expressed as a percentage, the push-pull signal is the differential strength given to the detector's total strength percentage. For example, in the light diffraction rate, the push-pull ratio is the relative ratio of the diffraction signal as the percentage of the total return intensity. Accurate mathematical derivatives can be found in Bouwhuis et al., 1985 Adam Hi lger, Ding Bristol, Chapter 2, "Disc System Principles,'. As shown in the third figure, there is a substitution relationship between process output and push-pull signal rate. The push-pull signal rate is shown as line 3 〇 〇 and the combined ordinate 3 〇 3 , and the process output is shown as line 302 and the combined ordinate 3〇4. For the present invention, a wall angle a of about 45 degrees provides premixing of process throughput and push-pull signal rates. It should be noted that if the design requires a higher process yield or a higher push-to-signal rate, the degree can be selected due to the relative reduction in performance of other features. % stomach Refer to the second figure again, the height of the side wall 2〇2 when there is no coating (also
