Latest Patents

Junichi Nakajo holds a patent for a "Recording medium detecting apparatus for distinguishing between a recording medium having a relatively high coercivity or a relatively low coercivity." This invention provides a technique for detecting a magnetic recording medium, such as a strip on a magnetic card. The apparatus distinguishes between cases where a magnetic strip has high coercivity and those with low coercivity. A magnetic head detects the existence and appropriate positioning of the magnetic strip, which is then fed to a permeability sensor. This sensor provides an output signal that is a function of the permeability of the magnetic strip. A circuit responsive to the output of the permeability sensor indicates whether the strip has high or low coercivity based on the sensor's output.
