Description
磁気記録装置側が予め定めたタイミングで磁気ヘッドのクリーニングを要求する場合には、磁気テープを一定の走行時間だけ走行させる前に磁気ヘッドの汚れが進行し、記録再生に支障をきたすことが考えられる。このように、磁気ヘッドのクリーニングのタイミングを予め所定の値に設定すると、適切なタイミングで磁気ヘッドのクリーニングを行うことができない点で改善の余地があった。
図1は、本発明に係る磁気記録装置の一実施形態を示す構成図である。図2は、磁気記録装置の構成を示すブロック図である。
磁気記録装置10は、筐体11を有している。筐体11の内部には、磁気記録・再生時に記録媒体として使用する磁気テープTの両端部が巻回された一対のテープリール12,13が設けられている。
例えば、図4に示す磁気記録装置20のように、磁気ヘッド14の表面を検出範囲と含むように色味検出センサ16を配置し、磁気ヘッド14の表面の変色を直接検出することで、該磁気ヘッド14のクリーニングのタイミングを検知できる構成としてもよい。このような構成の場合には被検出部を設ける必要がない。

15 被検出部
16 色味検出センサ
18 判断部

Claims (3)
- 走行する磁気テープに磁気記録・再生を行う磁気記録装置であって、
前記磁気テープに摺接するように取り付けられた磁気ヘッドと、
前記磁気ヘッドと同じAlTiC材料からなり、前記磁気テープに摺接するように設けられた被検出部と、
前記被検出部における前記磁気テープと摺接する前記表面の青色の波長の光を検出するブルーセンサとを備え、前記ブルーセンサにより前記被検出部の前記表面の色が特定の色に変化したことを検出した場合に、前記ブルーセンサから出力される検出信号を取得し、前記検出信号に基づいて前記磁気ヘッドのクリーニングを開始すべきタイミングを判断する判断部を備えていることを特徴とする磁気記録装置。 - 請求項1に記載の磁気記録装置であって、
被検出部を前記磁気テープに対して進退移動可能に保持する保持部材を備え、前記保持部材が進退移動することで、前記被検出部と前記磁気テープとの接触力を制御する磁気記録装置。 - 請求項2に記載の磁気記録装置であって、
前記被検出部と前記磁気テープとの接触力を前記磁気ヘッドと前記磁気テープとの接触力に対して10%以上とする磁気記録装置。
