Изобретение относитс  к области приборостроени , а именно, к технологии изготовле-, нн  носител , обладающего большой разрешающей способностью.The invention relates to the field of instrumentation, namely, to the technology of manufacturing, nn carrier with high resolution.

Известен способ изготовлени  термопластического носител  информации, основанный на поочередном нанесении на основу носител  провод щего, термопластического и защитного слоев. По такому способу изготавливают большинство известных термопластических носителей . Но в св зи с тем, что защитный слой предназначен в основном дл  защиты носител  в процессе его эксплуатации, в процессе изготовлени  воз.можны нарушени  целостности основы, что может привести к возникновению повышенных шумов.A known method of making a thermoplastic information carrier is based on alternately applying a conductive, thermoplastic and protective layer to the substrate of the carrier. By this method, most of the known thermoplastic carriers are made. But due to the fact that the protective layer is intended primarily to protect the carrier during its operation, during the manufacturing process, the integrity of the substrate may be disturbed, which can lead to increased noise.

Дл  уменьшени  веро тности возникновени  повышенных шумов при эксплуатации носител  по предлагаемому способу на основу предварительно нанос т с обеих сторон съемное защитное покрытие из пленкообразующего полимерного материала, после чего основу разрезают, перфорируют со стороны одного из съемных покрытий и снимают его, при этом нанесение провод щего, термопластического и защитного слоев осуществл ют на сторону, свободную от защитного покрыти , а аналогичное покрытие с другой стороны перед началом эксплуатации носител  также снимают.To reduce the likelihood of increased noise during the operation of the carrier according to the proposed method, a removable protective coating of film-forming polymer material is preliminarily applied to the substrate on both sides, after which the substrate is cut, punched from one of the removable coatings and removed. , thermoplastic and protective layers are carried out on the side free from the protective coating, and a similar coating on the other side is also removed ayut.

На фиг. 1 показана основа с нанесенным по описываемому способу с двух сторон защитным покрытием; на фиг. 2 - основа после разрезани ; на фиг. 3 - основа после перфорировани  защитного покрыти ; на фиг. 4 - основа после сн ти  верхнего защитного покрыти ; на фиг. 5 - полностью термопластический носитель с нижним защитным покрытием; на фиг. 6 - термопластический носитель без нижней кромки защитного покрыти .FIG. 1 shows a substrate with a protective coating applied by the method described on both sides; in fig. 2 - base after cutting; in fig. 3 - base after perforation of the protective coating; in fig. 4 - base after removing the top sheeting; in fig. 5 - fully thermoplastic carrier with a lower protective coating; in fig. 6 - thermoplastic carrier without lower edge of the protective coating.

В процессе изготовлени  на завершающей стадии основа может быть повреждена, что вызовет повышенные шумы информации приDuring the manufacturing process at the final stage, the base may be damaged, which will cause increased noise of information during

ее воспроизведении с носител , имеющего поврежденную основу. В св зи с тем, что термопластический носитель, как и аппаратура, в которой он используетс , обладают высокой разрешающей способностью, повысить ту.мыits reproduction from a carrier having a damaged base. Due to the fact that the thermoplastic carrier, as well as the apparatus in which it is used, has a high resolution, we increase the

могут даже микроскопические повреждени  основы. Нанесение на основу 1 защитных покрытий 2 и 3, которые в последующем могут быть легко удалены, позвол ет практически исключить веро тность ее повреждени  до начала эксплуатации.even microscopic damage to the base. The application of protective coatings 2 and 3 on the substrate 1, which can later be easily removed, makes it almost impossible to damage it before it is used.

После нанесени  защитных покрытий ос-юву разрезают (фиг. 2) и нанос т перфорацию (фиг. 3), окна 4 которой расположены в данпом случае со стороны покрыти  2. Далее s :pxнee защитное покрытие удал ют (фиг. 4) и осуществл ют поочередное панессние па оспову провод щего сло  5, термопластического сло  6 и защитного сло  7. Перед началом эксплуатации носител , т. е. перед его заправкой в аппаратуру, защитпое покрытие 3 также удал ют.After applying the protective coatings, the OS-YUVA is cut (Fig. 2) and perforation is applied (Fig. 3), the windows 4 of which are located in this case from the side of the coating 2. Next s: Alternatively, the alternating laminate of the conductive layer 5, thermoplastic layer 6 and the protective layer 7 are used. Before the carrier is put into operation, i.e., before its filling into the apparatus, the protective covering 3 is also removed.

На изготовленных описанным способом носител х повреждени  основы были настолько малы, что, например, при записи аналоговой информации отнощепие сигнал/шум на общем фоне засветки повышаетс  до 40 дб, в то врем  как в обычных случа х уровень этого отнощени  составл л 25-30 дб.On the carriers produced by the described method, the damage to the substrate was so small that, for example, when recording analog information, the signal-to-noise ratio on a general background of the illumination rises to 40 dB, while in ordinary cases the level of this ratio was 25-30 dB .

Описанный способ может быть использован практически дл  любого вида носителей, мен етс  лищь технологи  нанесени  защитных покрытий.The described method can be used for practically any type of carrier, the technology of applying protective coatings varies.
