<p>An improved recording head and recording medium particularly suited for use with perpendicular recording techniques. The recording head can be fabricated either as a single head or as a multi-track array. When fabricated as a multi-track array, the head includes a plurality of short main poles (70) spaced closely to one another and a common long flux closing pole (72) which completes a magnetic circuit between the main poles and recording medium (74). Each main pole (70) of the head array is individually addressable (38, 73) for the purpose of recording or reading by means of a flux gate arrangement. The flux gate may be utilizing so that the head operates either in a convention fashion by detecting the rate of change of induced flux or by detecting the magnitude of the induced flux.</p> |
