Abstract
A new method of observing external bit fields emanating from recorded media is proposed. Fields are magnetically transcribed to a magnetic film located some distance from a recording surface and are observed by means of Lorentz microscopy. Some observed field patterns are shown, and the magnetic flux flows are analyzed.
