ABSTRACT:
A method for controlling the status of a drive of an apparatus for reading from and/or writing to recording media is proposed. According to the method, a plurality of drive states are reported to a controller of the apparatus by applying drive state signals to an interface. To ensure that no drive state remains unnoticed by the controller, the drive state signals are applied to the interface for at least a predetermined period of time, even if one or more drive state actually lasts for a shorter period of time. To guarantee that the drive state reported to the controller is identical to the real state of the drive, one or more of the drive states, which last shorter than the predetermined period of time are artificially extended.
