Abstract:
A method for controlling an OPU and an optical data access apparatus are provided. A signal generator is configured to generate a servo signal in response to data access. A comparator is configured to compare a threshold level and the servo signal, and generate a control level if a level of the servo signal against the threshold level when the OPU is controlled. An adjustment unit is configured to adjust a control signal according to the control level. The OPU is controlled according to the adjusted control signal.
