    • To assure good data playback characteristics even when reading data from a magnetic tape having recording tracks at a narrow pitch, a data recording and/or reproducing apparatus is provided which includes a tape feeder 7 to feed a magnetic tape 100 in which data is recorded on recording tracks formed obliquely to the moving direction of the magnetic tape 100, a magnetic head 4 including a playback head having a width smaller than the recording width of the recording tracks to read data from the magnetic tape 100 and a record head to write data to the magnetic tape 100, a rotating drum 5 on which the magnetic tape 100 is scanned by the magnetic head 4, a rotating drum controller 6 to allow the playback head to scan the recording tracks at least two times in order to detect data recorded in the magnetic tape 100, and a read signal processor 3 to reproduce data recorded in the magnetic tape 100 from the data detected by the playback head having been allowed by the rotating drum controller 6 to scan the recording tracks the plurality of times.
    • 为了确保良好的数据播放特性,即使从具有窄间距的记录磁迹的磁带读取数据,也提供了一种数据记录和/或再现装置,其包括:带式馈送器7,用于馈送数据被记录在其上的磁带100 记录磁道与磁带100的移动方向倾斜地形成的磁道,包括具有小于记录磁道的记录宽度的重放头的磁头4,以从磁带100读取数据,以及记录头将数据写入 磁带100,其上由磁头4扫描磁带100的旋转滚筒5,旋转滚筒控制器6,允许重放头至少扫描两次记录磁道,以便检测记录在磁带上的数据 磁带100以及读取信号处理器3,用于从由旋转鼓控制器允许的由重放头检测到的数据再现记录在磁带100中的数据 6来多次扫描记录轨道。
