The present invention discloses a method of adjusting a rotation speed of an optical disc drive for a spindle motor controlled by a host to rotate and read an optical disc. First, it is determined whether the data read by the optical disc drive is in Mode 1 or Form 1 of Mode 2. If in Mode 1 or Form 1 of Mode 2, it is determined whether the frequency of read request commands output from the host is lower than a predetermined value or not.
