摘要： A magnetic recording/reproducing apparatus with a drum positioning mechanism is provided. The drum positioning mechanism performs track correction to rotate a tape guide drum about a given axis of rotation according to a travel speed of a magnetic tape to orient a head path of magnetic heads at a given angle relative to a lead member which guides movement of a lower edge of the magnetic tape wrapped about the tape guide drum so that the head path coincides with tracks recorded on the magnetic tape correctly. The drum positioning mechanism also performs lead correction to rotate the lead member through a given angle relative to a drum base to eliminate a shift of the lower edge of the magnetic tape from the lead caused by the track correction so that the lower edge of the magnetic tape follows the lead completely. The magnetic recording/reproducing apparatus may also be employed in a recording mode. In the recording mode, the head path is oriented by the track correction at a preselected angle to the lower edge of the magnetic tape.

摘要翻译：提供具有鼓定位机构的磁记录/重放装置。鼓定位机构执行轨道校正，以根据磁带的行进速度绕着给定的旋转轴旋转磁带引导鼓，以使磁头的头部路径以相对于引导件的引导部件的给定角度定向，磁带的下边缘缠绕在磁带引导鼓周围，使得磁头路径正确地与记录在磁带上的磁迹重合。滚筒定位机构还执行导向校正，以使引线部件相对于滚筒基座旋转给定的角度，以消除由磁道校正引起的磁带的下边缘与引线的偏移，使得磁体的下边缘磁带完全跟随导线。磁记录/再现装置也可以用于记录模式。在记录模式中，磁头路径以与磁带的下边缘成预定角度的磁道校正取向。
