INFORMATION REPRODUCING DEVICE FOR FERROELECTRIC RECORDING MEDIUM |
| 摘要 |
<p>A resonance circuit (17) is composed of a capacitor Cs of a ferroelectric layer (2) of a recording medium (1), and a resonator (14). A change of the capacitor Cs of the ferroelectric layer (2) is converted into a frequency of an oscillation signal by the resonance circuit. As the resonator (14), a resonance element having a high Q, such as an SAW resonator, is used.</p> |
