Apparatus and method for changing speed of recording on optical recording medium during recording operation

A method of changing a recording speed of an optical recording medium, the method comprising:

• checking a CRC signal which checks for a generation of errors on the optical recording medium, from absolute time in pregroove (ATIP) information which is detected from the optical recording medium during a recording operation;
• and
• stopping the recording operation with respect to the optical recording medium according to a comparison of a no good (NG) number generated by the checking of the CRC signal with a reference value, and changing the recording speed in a zone where the errors occur before restarting the recording operation.

An apparatus for changing a recording speed of a recording medium, comprising:

• a signal processing unit which monitors wobble signals of the recording medium during a recording operation with respect to the recording medium;
• and
• a speed control unit which changes the recording speed during the recording operation according to states of the wobble signals.
