Abstract: A control arrangement, for example, in a digital component that forms part of a system, draws an input current for its operation and is configured for monitoring an interface for any one of a group of commands and, upon detecting an issued one of the group of commands, operates the component for executing the issued command in an operational mode, and during an idle time on the interface, the control arrangement exclusively monitors the interface for any one of the group of commands such that the input current is limited to a leakage current. The component may draw less than 1 milliamp of current during the idle mode.

Abstract: A digital Storage Element is described. A device is configured including a Storage Element for access by a user responsive to a native control code. A processing arrangement executes a control program for controlling the overall device and executing at least a portion of the native control code as part of the control program for interfacing with the Storage Element. A programming arrangement is provided separate from the device for customizing a read channel within the Storage Element. Command, user interaction and data transfer execution are discussed for mitigation of potential mechanical shock effects. Status indications relating to the Storage Element are provided including head position and mechanical shock. Calibration, test and operational monitoring procedures, for using head position status, are described. Failure configuration monitoring is provided in tracking overall performance and design considerations.
