Problems solved by technology

However, in the wobble groove 12, the wobble of the junction 21 of the negative wobble and the positive wobble has a sharp change, which not only easily produces high-frequency interference, but also is not conducive to the manufacture of the disc substrate 11.
[0009] It can be seen that the above-mentioned existing optical information storage medium obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.
In order to solve the problems existing in optical information storage media, relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and general products do not have a suitable structure to solve the above problems. Obviously, it is a problem that relevant industry players are eager to solve.

Abstract

A storage media of optical information is prepared as winding a switching slot on base plate in spiral mode, arranging multiple first swing in first vibration amplitude and multiple second swing in second vibration amplitude being less then the first vibration amplitude on said swing slot for benefiting preparation of disc base plate.

Description

technical field [0001] The present invention relates to an optical information storage medium, in particular to an optical information storage medium with wobble grooves, which can modulate information to preset grooves, avoid high-frequency interference, and is beneficial to the production of disc substrates. Storage media. Background technique [0002] With the advent of the information and audio-visual era, optical information storage media has been widely used by the public, and with the continuous development of large-capacity demand, it has developed from the 650MB compact disc (CD) family to more than 4.7GB digital DVD family. [0003] Generally speaking, when reading and writing the optical information storage medium, it is necessary to accurately detect the linear velocity of each track on the optical information storage medium to control the motor speed. In order to achieve this purpose, most of the optical information storage media will form wobble grooves on th...
