A robot comprises a body, at least one traveling device, a suction cup and a pump module. The at least one traveling device disposed in the body is for causing the robot to move on a surface of a plate. The suction cup and the pump module are disposed in the body. The suction cup can move relative to the body. Upon an operation of the robot, the body, the suction cup and the plate form a closed space, and the closed space is kept at a negative pressure by use of the pump module.

A cleaner includes at least one cleaning component, a pump module, a driving module and a control system. The at least one cleaning component and the plate delimit at least one space. The pump module is connected to the at least one space to pump air out of the at least a space to form a negative air pressure in the at least one space so that the cleaner is sucked on the plate. The driving module is connected to the at least a cleaning component to drive the at least a cleaning component. The control system is coupled to the pump module and the driving module and controls the driving module to cause the at least one driven cleaning component to make a movement on the plate.

A cleaner adapted to clean particles on a plate is provided. The cleaner includes an active driver and a slave driver. The active driver includes a plurality of active cleaning wheels and a control system. Each of the active cleaning wheels includes a first magnet, and the first magnet has an even number of magnetic poles. The control system is electronically connected with the active cleaning wheels so as to control a rotation of the active cleaning wheels. The slave driver includes a plurality of slave cleaning wheels. Each of the slave cleaning wheels includes a second magnet, and the second magnet has an even number of magnetic poles. The plate is disposed between the active driver and the slave driver. The second magnets are disposed opposite to the first magnets, so that the active cleaning wheels drive the slave cleaning wheels to rotate by a magnetic force.

The system and method is used for CAV (Constant Angular Velocity) control format recording, whereas the existing disk data is recorded under CLV (Constant Linear Velocity) control format recording. When the PUH receives a laser driver signal, it generates a feed signal and a wobble signal. The feed signal is received by the automatic power control; thereafter the automatic power control generates a first control signal used for causing the laser driver to adjust the laser driver signal. After the ATIP decoder receives the wobble signal, the ATIP decoder generates and outputs ATIP decoded data to the CLV value detector. The CLV value detector receives ATIP decoded data and generates a CLV decoded data to the laser power control. The laser power control receives the CLV decoded data and generates a second control signal used for causing the automatic power control to adjust the first control signal.
