Magnetic reproducing system.

摘要

A magnetic material (1b-2) whose high frequency characteristics vary in response to a signal field recorded on a magnetic recording medium (1) is provided as a magnetic layer in a high frequency coupling circuit including the magnetic recording medium (1) and a reproduction head (5). The coupling degree of the high frequency coupling circuit noticeably varies with the change of the high frequency characteristics of the magnetic material (1b-2), thereby enabling the reproduction of the recorded signal by utilizing the change of the high frequency characteristics.
