The control circuit section is divided into two parts: an ATAPI controller section which deals with control between the ATAPI interface and drive interface, and a drive circuit section which controls the drive.

(1)ATAPI controller circuit section

The ATAPI controller circuit's reliability is improved by large-scale integrated circuit technology. The high-speed microprocessor (MPU) handles ATAPI interface control and drive control such as drive read-and-write control and single-beam control.

(2)Drive circuit section

The drive circuit section consists of the following circuits:

!Laser diode control circuit

!Signal reproduction circuit

!Servo/seek control circuit

!Rotation control circuit

!Drive miscellaneous control circuit

The DSP (digital signal processor) is used for the servo/seek control circuit to reduce the circuit amount, therefore this circuit is a simple configuration.

The drive circuit section executes operations such as seek, erase, record, and playback while the MPU controls the focus-tracking of the beam.
