Description
(54) НОСИТЕЛЬ ИНФОРМАЦИИ(54) MEDIA INFORMATION
- 1- one
Изобретение относитс к технике оптической записи, а именно к носител м информации .The invention relates to an optical recording technique, namely to information carriers.
Известен носитель информации, содержащий термопластический слой, основу, покрытую пленкой хрома, и светочувствительный слой, нанесенный на пленку хрома {1|. Недостатком известного носител вл етс его непрозрачность.Known information carrier containing a thermoplastic layer, a base coated with a film of chromium, and a photosensitive layer deposited on a film of chromium {1 |. A disadvantage of the known carrier is its opacity.
Известен более прозрачный носитель, содержащий основу, светочувствительное покрытие , нанесенное на основу, и термопластическое покрытие, нанесенное на светочувствительное 2. Однако отмечаетс сложность приготовлени смеси дл счеточувствительного покрыти .A more transparent carrier is known, which contains a base, a photosensitive coating applied to the substrate, and a thermoplastic coating applied to the photosensitive 2. However, the difficulty of preparing a mixture for a sensitive coating is noted.
Цель изобретени - повышение прозрачности и упрощение процесса изготовлени . Дл этого в носителе информации, содержащем основу , светочувствительное покрытие, нанесенное на основу, и термопластическое покрытие, нанесенное на светочувствительное, покрытие выполнено в виде сло фототюлупроводника п-типа и сло фотополупроводиика jO-типа, при этом на основу нанесен первый слой, удельное сопротивление которого меньше удельного сопротивлени второго С.ПОЯ.The purpose of the invention is to increase the transparency and simplify the manufacturing process. For this purpose, in a data carrier containing a substrate, a photosensitive coating applied to the substrate, and a thermoplastic coating applied to the photosensitive coating, the coating is made in the form of an η-type phototube semiconductor layer and a jO-type photoconductive layer, the first layer is applied to the substrate which is less than the resistivity of the second S.POY.
На чертеже изображен предлагаемый носитель .The drawing shows the proposed media.
Носитель содержит основу 1, светочувствительное покрытие 2, нанесенное на основу, и термопластическое покрытие 3, нанесенное на покрытие 2.The carrier contains a base 1, a photosensitive coating 2 applied to the substrate, and a thermoplastic coating 3 applied to the coating 2.
Покрытие 2 выполнено в виде сло 4 фотополупроводника п-типа и сло 5 фотополупроводника р-типа. Слой 4 нанесен на основу 1, а удельное сопротивление его меньше удельного сопротивлени сло 5.Coating 2 is made in the form of an n-type photoconductor layer 4 and a p-type photoconductor layer 5. Layer 4 is applied to base 1, and its resistivity is less than the resistivity of layer 5.
Предлагаемый носитель обладает прозрачностью , позвол ющей производить запись через основу, а считывание на просвет.The proposed carrier has a transparency that allows recording through the base, and reading through to the light.
