Reviews
- The answer to Sony's first Discman was the SL-XP 7, a portable CD player with the FF-1 fine-focus laser system and programmable playback in 16-bit resolution.
- While Sony splits the laser beam into three partial beams and uses the two secondary beams for tracking, the Technics' single beam is directed to a photosensitive sensor divided into four squares. By shifting the beam between these squares, the deviation from the data track is detected and corrected. The sum of all four squares gives the information signal (0 or 1). The SL-XP 7, launched in 1987, is still a remarkable piece of digital technology.
