摘要： An optical recording method and apparatus with different recording rates are provided for effectively increasing the average recording rate. The optical recording method includes the steps of: controlling a recording rate with a constant linear velocity (CLV) control mode; recording data; judging whether the recording rate has to be increased according to a rotating speed of a spindle motor or a recording position; and performing a process for changing the rotating speed if the recording rate is increased, and continuing recording data at the same recording rate if the recording rate is not increased. The step for changing the rotating speed includes the steps of: pausing recording data; registering a paused zone of a disc; determining a new rotating speed of the spindle motor, and driving the spindle motor at the new rotating speed; and linking recording zones to continue recording data at a new recording rate from the paused zone, when the rotating speed of the spindle motor is stable. Consequently, the invention can optimize the overall average recording rate by effectively utilizing the maximum rotating speed of the spindle motor in conjunction with the maximum recording rate.

摘要： An apparatus of detecting defects on an optical recording medium includes a defect signal generating circuit for generating a corresponding defect signal according to a surface defect of the optical recording medium, a first synchronous signal generator for generating a first synchronous signal, a defect signal locating circuit, a delay signal generating circuit, and an OR gate. The defect signal includes at least one pulse, whose width corresponds to the physical width of a surface defect. The delay signal generating circuit generates a delay signal corresponding to each pulse when the spacing between two adjacent pulses is smaller than a preset value. An OR operation is performed to the delay signal and the defect signal to obtain a defect extension signal. The first synchronous signal and a second synchronous signal for separating data recording sectors of the optical recording medium are employed to detect widths and addresses of surface defects.
