General Description

1.2.4 Control circuit section

Figure 1.4 is the block diagram of the control circuit section.

Figure 1.4 Control circuit section block diagram

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

(1) Controller circuit section

The controller circuit's reliability is improved by large-scale integrated circuit technology. The high-speed microprocessor (MPU) handles SCSI 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
