摘要：
The present invention resides in that two of three drivers are BTL-operated in pair to drive the motor for driving the tray and one of the two drivers and a remaining one driver are BTL-operated in pair to drive the other motors. Therefore, it is possible to construct a driver circuit for driving various drive motors within an optical disk drive device by adding only one driver to a conventional driver circuit and, thus, it becomes possible to make the drive circuit as a single chip IC.
