    Maintenance i. About the Optical Pickup The CD-77 uses a solid-state semi-conductor diode laser, mounted on a tracking servo-mechanism to play the disc. The laser illuminates the track of microscopic pits representing the digital data bits, while photo-diodes detect the reflected illumination from the disc and convert it into an electronic signal which is then decoded to recover the musical waveform in each stereo channel.
