Abstract:
1. A device comprising: a storage medium configured to store data; a motor supporting said storage medium and configured to control movement thereof; a head arrangement configured for movement to selectively access the storage medium in a data access mode and for movement to a non-data access position wherein the head is not positioned to access the storage medium; a first dedicated input that is dedicated for receiving a first sensor related input signal; and a processing arrangement programmed to (i) execute said data access mode by cooperatively controlling said motor and said head arrangement, (ii) monitor said first sensor related input signal for occurrence of a predetermined value of a first minimum time duration, and (iii) responsive to detection of said predetermined value, at least move the head arrangement to said non-data access position, said processing arrangement being further configured for maintaining said head arrangement in the non-data access position so long as the first sensor related input signal remains at the predetermined value, subsequent to initially moving the head arrangement to the non-data access position; wherein the first sensor related input signal is a digital signal and the selected value of the first sensor related input signal is a first one of two states, and said processing arrangement is further configured for detecting an initial occurrence of a second one of the two states while maintaining said head arrangement in the non-data access position and, responsive to detecting the second state, monitoring said first sensor related input signal for any return to said first state, during a second minimum time duration that is measured from said initial occurrence of the second digital state, while continuing to maintain the head arrangement in said non-data access position over the second minimum time duration.
