How does a CD player motor work?

The motor in a CD player (or any "disk medium" player) is necessary to spin the CD at a speed that the laser pickup can "read" the data on the disk. As the laser pickup moves along the surface scanning the disk, it causes the motor to slow down as it gets further out on the disk so the data is still read at the correct speed. Or just the opposite, reading from the outside egde of the CD the laser needs to read constitantly so the disk motor speeds up for the smaller circumference of the data on the disk. A combination of elecltronics monitors the motor speed, the data being read and the location of the laser computing the time necessary.

After the machine is configured, change the MBR Security back to "enable" in order to prevent virus programs from being written to the MBR. This method has been sucessful for me on HPCompaq machines when reinstalling the XP operating system from the reload CDs.
