Texas Instruments, or TI, is one of the largest and most influential US companies in the electronics industry.
How accurate and robust is this optical system? Imagine travelling in a car going over 40 million miles per hour and never straying outside of your lane. That is the feat that a Blu-ray drive does every time you put a disc in, hour after hour. Optical drives achieve this amazing feat with a well designed optical system known as the optical pickup head. How a complete optical system with real-time feedback fits within such a tiny package is a feat of engineering that took the pioneers of optical data systems decades to develop and perfect, and deserves a closer look.
