Abstract: A contact management and control system for managing contact events associated with an enterprise detects a contact event and actuates a contact manager to retrieve information pertaining to the contact event from a contact library. If new information is associated with the contact event, the contact library is updated with the new information. Information in the updated library is subsequently disseminated across the enterprise. A contact event has a set of identifying parameters. When a contact event is detected, the event's parameters are compared to a set of predetermined values to detect a match. If a match exists, then, in response to the contact event, a number of commands are executed according to a predetermined set of at least one rule. The contact information is updated in the contact library, and the update disseminated across the enterprise to appropriate client stations and users having privilege over the updated contact information.

Abstract: A mass storage drive removably supports a mass storage element and includes a data head having an output for reading tracks of main data elements. The data head, which can be an optical head, is movable in a predetermined auxiliary path relative to the substrate for scanning a unique machine-readable serial identifier in auxiliary data containing at least 200 bits of information in one or more tracks being exclusive of main data tracks. The mass storage drive includes a head circuit connected to the data head output and having a main amplifier with an output for signaling main data elements in response to the data head, the circuit having a separate auxiliary put for signaling the auxiliary data elements in response to the data head output. The head circuit can include an auxiliary amplifier for driving the auxiliary output.
