Digital processing of sensor signals for reading binary storage media

摘要

An apparatus and method for processing an electrical signal produced by one or more sensors in a device for reading binary storage media, whereby the signal represents a set of successive stored binary values. Digital values which represent a selection of two or more samples of the electrical signal are combined using digital circuits to produce an intermediate digital representation which is then processed to derive one of the binary values. The combining and processing steps are repeated for other selections of the samples to obtain the desired set of successive stored binary values.
