Problems solved by technology
However, when the system receives a drawing command from the 111th track to the 120th track again, the sled motor 130 needs to use the transmission gear to drive the optical read-write head 10 to move inwardly from the 210th track to the 111th track and then Begin to perform the drawing action outward to the 120th track. At this time, because the sled motor 130 uses the transmission gear to drive the optical read-write head 10 to move inward to a predetermined track, the backlash error of the transmission gear will cause There is a pattern gap 20 visible to the naked eye as shown in the figure between the 111th track and the 110th track

Embodiment Construction
[0031] See image 3 , is a flow chart diagram of the method for controlling the drawing of the disc label pattern developed by the present invention to improve the deficiencies of the known technology, because the hardware environment of its application and figure 1 The hardware environment shown is not different, so it will not be described again, and the main difference lies in the control method. The main steps are:
[0032] First, the user puts the optical disc into the optical drive, and faces the optical pickup in the optical drive with the label surface, and then controls the optical pickup to move along a first track jumping direction to the optical disc. A first predetermined track number range of the label surface of the sheet is drawn, wherein the first predetermined track number range has a first upper bound track number and a first lower bound track number, and the first track jump direction It is to move from the first lower bound track number to the direction o...

A method for controlling volume label pattern description of optical disc includes controlling optical read / write head in optical drive to move along the first track jump direction and to carry out pattern description on the first preset track number range with the first top boundary track number and the first bottom boundary track number of volume label face, controlling optical read / write head to move to the second track number along the second track jump direction then moving along the first track jump direction and carrying out pattern description on the second preset track number range for confirming the second track jump direction.
Description
technical field [0001] The invention relates to a control method for drawing a disc label pattern, especially a control method for drawing a disc label pattern applied to a disc recorder. Background technique [0002] It is a common practice for computer users to use a CD recorder to back up data. However, when the burning of the CD is completed, the user finds that there is no suitable pen at hand for marking, or even the handwriting is not clear and professional enough. Even if the disc label sticker made by the printer is used, it is easy to cause uneven sticking, generate air bubbles, and then make the center of gravity of the disc unbalanced, resulting in difficulties in reading. In view of this, some manufacturers have developed a CD label drawing technology to solve the problem of CD labels. [0003] It mainly needs to prepare a special CD. The data burning surface of this special CD is the same as that of a normal CD, but the label surface is coated with a special ...
