The Inner Working Of A CD Changer: How It Reads And Processes Discs
In this section, we will delve into the intricate inner workings of a CD changer and explore how it reads and processes discs.
The primary component responsible for reading and processing discs is the optical pickup unit (OPU). The OPU consists of a laser diode and a lens system. When a disc is loaded into the CD changer, the OPU emits a laser beam onto the reflective surface of the disc.
As the disc rotates, the laser beam reflects off the surface and is then captured by the lens system. The lens system focuses the reflected laser beam onto a photodiode. The photodiode converts the light signal into an electrical signal, which is sent to the digital signal processor (DSP).
The DSP then decodes the electrical signal, separating it into audio data and error correction data. The audio data is converted into analog signals that can be amplified and played through the speakers. Meanwhile, the error correction data is used to correct any imperfections or scratches on the disc’s surface, ensuring a smooth playback experience.
Additionally, the CD changer may utilize a buffer memory to temporarily store data, reducing the chance of audio interruptions during disc changes or minor reading errors.
Understanding the inner workings of a CD changer provides valuable insight into the technology behind this audio playback system.
