A method of improving readability in an optical drive is disclosed. In one aspect, the present disclosure teaches a method of improving readability in an optical drive including monitoring a compact disc (CD) media for tracking errors using a differential push-pull (DPP) method during an input/output (I/O) operation in an optical drive. The method further includes determining whether a tracking error is above a predetermined error threshold or if a read error has occurred. In response to a read error or tracking error, the method further includes switching from the DPP method to a three-beam tracking method based on the determination.
