Abstract: 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.
