| description | To provide a magnetic disk device and a controlling method for the magnetic disk device capable of suppressing deterioration in quality of data written to the magnetic disk drive.SOLUTION: A magnetic disk device includes a disk media and a controlling circuit. The disk media includes a first area including a first track. The controlling circuit controls a writing operation of the first data to the first track. The controlling circuit can execute an error correction encoding for the first data at the operation. The controlling circuit executes a first determination whether or not the written first data is protected by the error correction encoding, and sets a second track position adjacent to the first track on the basis of the result of the first determination.SELECTED DRAWING: Figure 8
【課題】磁気ディスク装置にライトされたデータの品質の低下を抑制すること。【解決手段】磁気ディスク装置は、ディスク媒体と制御回路とを備える。ディスク媒体は、第１のトラックを含んだ第１領域を備える。制御回路は、第１のトラックに第１のデータをライトする動作を制御する。制御回路は、当該動作の際に第１のデータに対して誤り訂正符号化を実行することができる。制御回路は、ライトされた第１のデータが誤り訂正符号によって保護されているか否かの第１の判定を実行し、第１のトラックに隣接する第２のトラックの位置を第１の判定の結果に基づいて設定する。【選択図】図８ |
