号の再生を行なう回転磁気ヘツドと、この回転磁
気ヘツドで記録された信号トラツク上を走査して
信号の消去を行なう回転消去ヘツドとを取付けた
回転ドラムを備えた磁気記録再生装置において、 前記回転消去ヘツドの幅を、Ｗの２倍以上の値
｛ただし、Ｗ＝（前記回転磁気ヘツドの数）×（
前記信号トラツクのピツチ）÷（前記回転消去ヘ
ツドの数）｝になるよう設定し、 前記回転消去ヘツドが前記信号トラツク上の略
全幅を２回以上走査して信号を消去するよう構成
したことを特徴とする回転消去ヘツド装置。[Claims for Utility Model Registration] A rotating magnetic head for recording signals on a tape and reproducing the recorded signals, and erasing the signals by scanning the recorded signal tracks with the rotating magnetic head. In a magnetic recording/reproducing device equipped with a rotating drum to which a rotating erasing head is attached, the width of the rotating erasing head is set to a value that is at least twice W {where W = (number of rotating magnetic heads) x (
(pitch of said signal track) ÷ (number of said rotating erasing heads)}, and said rotating erasing head scans substantially the entire width on said signal track two or more times to erase the signal. A rotating erasing head device with special features.
