Abstract
We propose to use the stray field of a magnetic domain (e.g, a bubble) for magnetic recording. It is shown that these stray fields are large enough to write information into a conventional disc or tape. An experiment in which an audio signal is recorded on a conventional tape with the aid of a stripe domain is described. We consider the feasibility of an integrated recording head for "one head per track recording" by using a multitude of bubbles in one crystal plate as well as the possibility of realizing a scanning head for video recording. Our preliminary experiments demonstrate the feasibility of recording based on this new principle.
