Patent ID: 8284641

Claim:
An optical disc apparatus using an optical disc as an information recording medium, said optical disc apparatus comprising: an optical pickup; a tracking servomechanism that generates a tracking actuator drive signal on a basis of a tracking error signal obtained from the optical pickup, and controls a position of an objective lens included in the optical pickup; a sled motor that rotates and thereby moves the optical pickup in a radial direction; a low-pass filter that extracts a low-frequency component of the tracking actuator drive signal; and a sled drive signal supplier that compares a level of the low-frequency component with a predetermined level to generate a sled pulse signal for controlling a sound skip of the optical disc, and outputs the sled pulse signal as a drive signal for the sled motor, the sled pulse signal having a level corresponding to the level of the low-frequency component, wherein the sled drive signal supplier comprises: a comparator that compares the level of the low-frequency component with the predetermined level; a pulse level setting circuit that selects a first pulse level based on a result of the comparing indicating that the level of the low-frequency component is lower than the predetermined level, and selects a second pulse level based on the result of the comparing indicating that the level of the low-frequency component is equal to, or higher than the predetermined level, the second pulse level being higher than the first pulse level; a pulse generating circuit that generates the sled pulse signal having the level corresponding to a result of the selecting by the pulse level setting circuit; and a terminal outputting the drive signal, and wherein the optical disc apparatus further comprises a control circuit that switches a connection route between the low-pass filter and the terminal, the connection route including a first connection route indicating a route between the low-pass filter and the terminal includes the pulse generating circuit, and a second connection route indicating the route between the low-pass filter and the terminal does not include the pulse generating circuit.
