Summary:To provide a recording/reproducing device and a recording/reproducing method capable of easily suppressing a decrease in a positioning accuracy of a magnetic head.SOLUTION: A recording/reproducing device includes a magnetic head H including a recording/reproducing element RWD that records or reproduces data for a data track DT and a servo reproducing element SRD that reads a servo pattern SP. Depending on a position of the data track DT to be recorded or reproduced for data in a data band DB, two servo reproduction elements SRD from the servo reproduction elements SRD of the magnetic head H are selected, and the magnetic head H is controlled to be positioned using the reading result of the servo pattern SP by the selected servo reproduction element SRD.SELECTED DRAWING: Figure 16 【課題】磁気ヘッドの位置決めの精度の低下を簡易に抑制することができる記録再生装置及び記録再生方法を得る。【解決手段】記録再生装置は、データトラックＤＴに対するデータの記録又は再生を行う記録再生素子ＲＷＤとサーボパターンＳＰを読み取るサーボ再生素子ＳＲＤとを含む磁気ヘッドＨを備え、データバンドＤＢ内のデータの記録又は再生の対象とするデータトラックＤＴの位置に応じて、磁気ヘッドＨのサーボ再生素子ＳＲＤの中から２つのサーボ再生素子ＳＲＤを選択し、選択したサーボ再生素子ＳＲＤによるサーボパターンＳＰの読み取り結果を用いて、磁気ヘッドＨを位置決めする制御を行う。【選択図】図１６
