Features Accurate Data Reading: The sophisticated head of the Play-Station 2 Accessories ensures precise data reading from game discs, allowing for an immersive gaming experience. Enhanced Cleaning Care: Take special care when cleaning the inside of the CD drive to maintain the optimal performance of the essential head part. Comprehensive Head Design: The head includes a generator (diode), semi-reflective prism, objective lens, and photoelectric diode, working together to deliver efficient data retrieval. Precise Light Convergence: The light emitted from the generator passes through the semi-reflective prism and converges on the objective lens, creating extremely tiny points on the CD for accurate data extraction. Efficient Reflection Handling: With its reflective material, the disc reflects light back onto the objective lens, which then illuminates the semi-reflective prism, ensuring reliable data output. Features: La-ser head mainly includes la-ser generator (also known as la-ser diode), semi-reflective prism, objective lens, lens and photoelectric diode. Since prism is semi-reflecting, light beam can not goes through it completely, but reached the photo-diode through the lens. Due to the disc surface is uneven point to record data, so the reflected light will be in different directions; people define different direction of signal as "0" or "1", light-emitting diodes gets the data of "0", "1", and ultimately resolve them as the data we need.
