Abstract: A method corrects track misregistration attributable to out-of-plane motions of a rotating disk in a hard disk drive, and includes the steps of measuring a base plate-roll-bias angle between the rotating data storage disk and the head arm with a precision measuring device, and connecting the head arm and load beam at a roll-bias angle selected to minimize track misregistration attributable to the roll-bias. A number of connection arrangements and structures are presented in order to achieve the desired reduction in track misregistration.

Abstract: A system and method for controlling the security of data in a central high speed data processing unit (CPU) by electronically sensing and comparing all operating or control statements coming into the CPU from terminal devices with a vocabulary of all statements unacceptable for security reasons which unacceptable statements are stored in a remote secondary computer system. The security of the data is also controlled by electronically sensing and comparing all operating and problem steps loaded into the CPU from library devices with a collection of identifiers known to identify all correct versions. The reaction to security dangers found in either sensing and comparing method is to exert predetermined counteraction to preclude unauthorized removal, alteration, destruction or inspection of problem data and/or procedures.The system includes a plurality of sensors which monitor operating control statements, operating and problem steps or procedures and physical switches on the CPU control panel.
