专利摘要:
The invention relates to the field of information storage, namely, optical recording disc media. The aim of the invention is to improve the quality of the carrier by reducing the effect of defects on the transparent plastic substrate. The transparent plastic base 1 has a central annular zone 2 located between the outer zone 3 and the inner zone 4. The base 1, on the side of zone 2 opposite to the reproduction side, is made with a spiral track and is covered with a reflective layer. The outer zone 3 is made completely or partially matte, which provides for masking of optical defects of the base 1, which could impair the visual perception of the carrier. 3 hp f-ly, 2 ill.

1
The invention relates to the accumulation of information, namely disk optical recording media.
The known carrier is in the form of an optical video disc, on one side of which a reflective coating is applied, and on the other side of the transparent disk an internal zone is formed, which is then matted.
However, this carrier has no external zone, which reduces the convenience of its operation.
A record carrier in the form of a disk is known, on one side of which a concentric information zone is formed, on the opposite sides of which the inner and outer zones are formed, which are then matted. .,.
However, these discs are made with a transparent outer zone, and the reflective coating is present only on the recording tracks. This impairs the appearance of the product due to the influence of the flaw.
comte transparent base.
The purpose of the invention is to improve the quality of the optical recording medium disc by reducing the effect of defects on the transparent plastic disc base.
Figure 1 shows one of the possible options for disk optical recording media; figure 2 - possible options for the implementation of its external and internal annular zones of a transparent plastic disk base
The optical recording medium disk contains a transparent plastic disk base 1 provided with a central annular zone 2 located between the outer annular zone 3 and the inner annular zone A. In this case, the basal 1 from the side of zone 2 opposite to the reproduction side is reflected, and has covered with reflective metal ::; tally layer. In addition, the disk of the base 1 is complete with transitional ring zones 5 and 6 between the central ring zone 2 and zones 3 and 4,
In optical disc media. The outer annular zone 3 of the base 1 is made matte; in this case, it can be made fully or partially with the mat.
In disk media, the outer zone 3 of the base 1 can be made with

The inner annular zone 4 may also be fully matted in full or in part.
