Verfahren zur UEberwachung von Aufzeichnungstraegerantrieben

摘要

A computer peripheral device having related mechanical and electrical functions such as a magnetic media transport is analyzed by combining tachometer signals indicative of a mechanical function with data signals from the electrical functions. Such data signals can represent formatting of data on the media while the tachometer pulses indicate capstan rotation used for media transport. In tape systems, data-signal formatting is usually generated by successive motions of the media.
