Problems solved by technology

However, the structure of the super-resolution near-field structure recordable disc is different from that of the BD-R disc. The recording medium originally used for BD-R may not be suitable for recording the super-resolution near-field structure.

Embodiment 1

[0019] The recordable Blu-ray super-resolution near-field optical disc of the present invention sputters the first protective layer 2, the mask layer 3, the second protective layer 4 on the optical disc substrate 1 in sequence, and spin-coats a layer on the second protective layer 4. The recording layer 5 is formed by sputtering the reflective layer 6 on the recording layer 5; its process is roughly:

[0020] Use magnetron sputtering equipment on the clean disc substrate 1, the vacuum degree is 1.0×10 -4 Pa, RF magnetron sputtering SiN to form a first protective layer 2 with a film thickness of 120nm, then magnetron sputtering an antimony mask layer 3 with a film thickness of 20nm, and magnetron sputtering a second protective layer 4 with a film thickness of 20nm; On the second protective layer 4, use a spin coater to spin-coat one layer of recording layer 5, the material of this recording layer is an organic dye (DYE), and the film thickness is 60nm. On the recording layer 5,...

Abstract

The invention relates to a recordable blue-ray super-resolution near-field structure disk which comprises a disk substrate, a recording layer and a metal reflective layer, and is characterized in that a first protective layer, a mask layer and a second protective layer are further arranged between the disk substrate and the recording layer, the material of the recording layer is an organic dye, and the thickness of the recording layer is 60-120nm, the thickness of the first protective layer is 100-170nm, and the thickness of the second protective layer is 10-30nm. When a disk uses a blue-ray (405nm) recording device for recording, the size of recording points on the recording layer of the organic dye of the disk is smaller than that of BD-R, thereby being capable of acquiring higher storage density.

Description

technical field [0001] The invention relates to the technical field of near-field optical storage, in particular to a recordable Blu-ray super-resolution near-field optical disc, which uses organic dyes as the recording layer of the super-resolution near-field optical disc, and uses the existing Blu-ray recording equipment to reduce the recording point so as to greatly Increase the storage density of optical discs. Background technique [0002] With the rapid development of information technology, it is necessary to process and save a large amount of data and audio and video information such as sound, graphics, and images, which makes people's requirements for information storage develop in the direction of high density, large capacity, high speed and low cost. . The optical storage technology represented by the optical disc has been developed for more than 20 years, but the traditional optical disc storage is far-field optical storage. Due to the diffraction effect, the d...
