摘要： The specification disclosed a method that controls the access times of an optical disc and discs of the same. The method includes the following steps. First, an optical disc drive obtains the addresses of a life flag and a medium key block (MKB) by reading a private flag of an optical disc. The life flag and the MKB are used to control the access times of the optical disc. After confirming the addresses of the life flag and the MKB, the optical disc drive obtains an optical power signal to determine the power that should be used to read the MKB. When the optical disc drive uses the appropriate reading power to access the MKB, the recognizable number of access times in the MKB data is reduced, and the medium key signal is extracted to be confirmed if it is recognizable to restore the main data.

After confirming the addresses of the life flag and the MKB, the optical disc drive obtains an optical power signal to determine the power that should be used to read the MKB. When the optical disc drive uses the appropriate reading power to access the MKB, the recognizable number of access times in the 4KB data is reduced, and the medium key signal is extracted to be confirmed if it is recognizable to restate the main data.

摘要： This specification discloses a recordable optical recording medium containing preinstalled information, the method of reading the preinstalled information, and the circuit thereof. The recordable optical recording medium containing preinstalled information is a substrate with a spiral pregroove. Microscopically, the pregroove has regular wiggles. They are featured in containing a first waveform, a second waveform, and a third waveform with the same fundamental wave cycle. The duty cycle of the first waveform is 1. The duty cycles of the second and third waveforms are distinct. The combinations of these duty cycles are used to record the preinstalled information. Moreover, the invention discloses a method and circuit of reading the preinstalled information. After obtaining the wobble signals, the method further takes the steps of phase corrections, integrations, and resetting to more accurately obtain the preinstalled information.
