Magnetic reproduction system.

摘要

A capacitance element (10) includes as an interelectrode substance a magnetic body (11) for detecting a magnetic field formed by a magnetic recording medium (21). A tuned circuit (10, 14) includes the capacitance element as a tuning element and receives a signal from a high-frequency oscillator (16). The magnetic characteristics of the magnetic body change with changes in the magnetic field formed by the magnetic recording medium. The high-frequency signal output from the tuned circuit changes with changes in the magnetic characteristics of the magnetic body. A detecting circuit (20) detects the changes in the high-frequency signal output so as to reproduce signals recorded on the magnetic recording medium.
