INFORMATION RECORDING/REPRODUCING DEVICE |
| 摘要 |
<p>A probe group (20) is composed of, for instance, four probes (17A-17D) adjacently arranged, and one modulation circuit (31) is arranged for each probe group (20). At the time of recoding information, a changeover switch (32) connects one of the four probes (17A-17D) with the modulation circuit (31), and subsequently changes the probes to be connected with the modulation circuit (31) while reciprocal movement of a recording medium is being controlled.</p> |
