摘要： A method of and apparatus for obtaining digital expression of analog signals, in particular signals produced by «reading» (i.e., transducing) head-positioning information recorded on storage media, for example magnetic recording media. Head-positioning signals (36, 38) constitute signals bursts which are processed to obtain pulses whose width is dictated by the amplitude of the detected bursts, and the pulse width in each instance is expressed digitally by using the magnitude of the pulse to drive a counter-timer (61). The resulting count integrally embodies a digitized representation of the initial analog signal burst, which is directly available for further processing by digital means and for storage in digital memory apparatus.

摘要： A magnetic core structure for a transducer head for digital data storage, particularly on tape, has a magnetic circuit having a gap (16,116) and a write pole (12) extending across the whole width of the gap and a read pole (14) divided into a medial strata (20;120) and two flanking strata (18,22;118,122) which overlap the medial strata over limited areas (A) in which areas there is non-magnetic isolation means (24,26;124,126). The areas (A) are limited in size to an amount which limits the transfer of magnetic flux from the flanking strata (18,22;118,122) to the medial strata (20;120) through the isolation means (24,26;124,126) at said areas to less than about ten percent of the total magnetic flux in the magnetic circuit.
