A 5000: 1 Scale Model of the Magnetic Recording Process
D. L. A. Tjaden, Jos Leyten · Journal of the SMPTE · 1965
Although magnetic recording is widely used for a variety of purposes, little is known about the actual process by which signals are recorded in the thin magnetic coating of the tape. A better understanding of the process is being sought through study with the aid of a model of the tape and recording head which is scaled up 5000:1 and in which the distribution of the magnetization over the thickness of the coating is measured.
