Title: Method using change of groove wobbling range to generate control signals and compact disk product
Inventor: WANG SHYHYEU
IPC: G11B7/007
Filed: 2003-01-16
Abstract: The present invention relates to a method for generating compact disk control signals and its compact disk product, in which the change of pre-groove wobbling range of a recordable or rewritable compact disk is utilized to generate signals for controlling the compact disk rotation speed and representing the data segments in the compact disk. Based on the compact disk of the present invention, the pre-groove comprises a high wobbling range groove shape and a low wobbling range groove shape respectively representing '1' or'0' of the address information in the compact disk. Because the method only changes the wobbling range of the groove, it is not necessary additionally carve frequency modulation signal or between grooves, or abruptly change the wobbling direction of the groove to reflect phase modulation signal. The geometric shape of the groove can endure repeated writing and high heat influence caused by wiping. Therefore, digital signal can be correctly written into the correct location, thereby increasing the quality of recorded signal and simplifying the manufacture of master mold of the compact disk.
