Reflects back by the mirrored surface of the CD. When the tray is closed, the laser fires short pulses of beam, and if there is a CD on the tray, the beam Therefore, the next course of investigation was to determine how the system detects the CD in the first place. Obviously, if the system does not detect a CD in the tray, then it will not energise the spindle motor. Just to see what would happen without a CD, I removed it and closed the tray and exactly the same sequence of errors appeared. If there was no disc inserted, then why did the system try to read the table of contents from it in the first place? I thought the firmware programming was poor. The CD player computer indicating that it did not find a disc seemed strange.
