Title: Pao-Ping Ma: Innovator in Optical Recording Technology
Introduction
Pao-Ping Ma is a notable inventor based in Hsin-Chu, Taiwan. He has made significant contributions to the field of optical recording technology, holding a total of 2 patents. His work focuses on enhancing the efficiency and effectiveness of automatic power control in optical devices.
Latest Patents
One of his latest patents is titled "Apparatus and method for automatic power control." This invention discloses an optical recording apparatus that utilizes a low-speed, peak-hold circuit to obtain and output a maximum of a front photodiode output signal during a predetermined window. The system allows the maximum peak-hold signal to stabilize before being sampled and held in a sample and hold circuit. A reset clears the signal and reinitializes the peak-hold circuit. The feedback controller unit then outputs the required current level into a driving unit for producing desired recording pulses into a laser diode for recording information pits into an optical disc.
Another significant patent is the "Automatic power controller." This device includes a photo detector that detects the output power of the laser light source and generates a detection signal. A comparator compares this detection signal with a reference signal, outputting a comparison signal. The system features a gain-adjustable amplifier that generates an output signal, ensuring that the voltage difference between the steady-state voltage of the comparison signal and the reference signal remains substantially unchanged. This innovation allows the automatic power controller to rapidly reach a new steady state while changing the laser output power.
