Embodiment Construction

[0036] An optical information storage medium according to a preferred embodiment of the present invention will be described below with reference to related drawings.

[0037] The optical information storage medium of the present invention includes a write-once type single-sided double-layer digital laser video disc (DVD-R). In this embodiment, a single-sided, double-layer DVD-R disk 20 is taken as an example to illustrate a preferred embodiment of the optical information storage medium of the present invention.

[0038] Such as figure 2 As shown, a single-sided double-layer DVD-R disc 20 includes a first substrate 21, a first recording layer 22, a first reflective layer 23, a spacer layer 24, a second recording layer 25, and a barrier layer 26 , a second reflective layer 27 , and a second substrate 28 .

[0039] Among them, the first recording layer 22 and the first reflective layer 23 can be collectively referred to as the first recording layer L 0 , and the sandwich stru...

Description

technical field [0001] The invention relates to an optical information storage medium, in particular to a single-sided double-layer DVD-R optical information storage medium. Background technique [0002] With the advent of the information and multimedia era, the storage density and capacity of the storage media required by electronic products are also increasing. Traditional storage media can be roughly divided into two categories, namely magnetic recording media and optical recording media. At present, the market is dominated by optical recording media, which include CD-ROM, CD-R, CD-RW, digital DVD-ROM, DVD-R, DVD-RW, DVD+RW, and DVD-RAM )etc. [0003] Facing the ever-increasing amount of video and audio information, increasing the data capacity of optical discs has always been the goal pursued by the industry. And because DVD has a larger data storage capacity than CD, it has occupied a certain proportion in the optical storage media market. The current DVD has diffe...
