Zusammenfassung:To provide a magnetic recording/reproducing device capable of reducing the transfer of contaminants to a magnetic head.SOLUTION: A magnetic recording/reproducing device 1 includes: a disk-shaped magnetic recording medium 2; a motor 3 for rotationally driving the magnetic recording medium 2; a magnetic head 4 having a magnetic head element for reading information and a magnetic head element for writing the information with respect to the magnetic recording medium 2; and a bias circuit for supplying a predetermined bias voltage to the magnetic head element for reading the information. The magnetic recording medium has a magnetic layer and a carbon protection layer in this order on a substrate. The bias circuit supplies a voltage of -0.2 V to -1.0 V with respect to the potential of the magnetic recording medium to the magnetic head elements.SELECTED DRAWING: Figure 1 【課題】磁気ヘッドへの汚染物の転写を低減できる磁気記録再生装置を提供する。【解決手段】磁気記録再生装置1は、円盤状の磁気記録媒体2と、磁気記録媒体2を回転駆動するモータ3と、磁気記録媒体2に対する情報の読み出しを行う磁気ヘッド素子と情報の書き込みを行う磁気ヘッド素子とを有する磁気ヘッド4と、情報の読み出しを行う磁気ヘッド素子に所定のバイアス電圧を供給するバイアス回路と、を備える。磁気記録媒体は、基板上に磁性層と炭素保護層をこの順で有する。バイアス回路は、磁気記録媒体の電位に対し、-0.2V~-1.0Vの電圧を磁気ヘッド素子に供給する。【選択図】図1
