Optical Pickup Unit (Laser)
The 'Not Reading' symptom is the result of the laser diode's gallium arsenide layer degrading over time, leading to insufficient power for disc detection. If the laser cannot track the spiral data path or focus the beam, the system logic often prevents the eject cycle from initiating correctly as it fails to confirm the disc's rotational state. This component is the primary optical sensor responsible for reading the digital data from the CD.

CD Drive Loading Belt
The rubber belt responsible for transferring torque from the load/unload motor to the slot-loading rollers loses elasticity and develops a 'set' or stretches. This lack of tension prevents the mechanism from generating enough force to release the spindle clamp and push the CD out of the slot. A slipping belt is the most common cause of a physically stuck disc in slot-loading Bose units.

Complete CD Traverse Mechanism
When both optical and mechanical failures occur simultaneously, replacing the entire internal traverse assembly is the most reliable forensic solution. This assembly includes the spindle motor, tracking motor, laser pickup, and the loading gears/rollers, ensuring that timing issues or gear-tooth wear are addressed alongside the laser failure.
