ABSTRACT:
Manual actuation of a stop/eject button on a computer causes a signal to be sent to both the computer's operating system and to a wireless communication controller. The operating system interprets this signal in a manner analogous to a conventional signal to open the drawer, or door, of a compact disk drive device when a compact disk is not currently present in the drive device. If a compact disk is present in the device, the operating system ignores the signal. In this case, the communications controller operates in a normal fashion to interrupt access to the compact disk, instruct the operating system to unmount the disk, and thereafter eject the disk by opening the drive door.
