    • The present invention provides a magnetic recording and reproducing apparatus, a magnetic recording and reproducing method, and a thin film magnetic head that enable a good contact between elements and a recording medium with a reduced track pitch even if the number of head channels is increased, thereby realizing high recording density and high transfer rate.At least one multitrack write head having N (N is an integer of 2 or more) write elements arranged along a track width direction in an integral fashion and at least one multitrack read head having L (L is an integer equal to or more than N) read elements arranged along the track width direction in an integral fashion are formed on the rotary drum. The multitrack write head writes signals to a group of N tracks aligned parallel on the magnetic tape during one rotation of the rotary drum, and the multitrack read head reads the group of N signal tracks by the use of any one of the L read elements.
    • 本发明提供了一种磁记录和再现装置,磁记录和再现方法以及薄膜磁头,即使磁头通道的数量增加,也能够实现元件与轨道间距减小的记录介质之间良好的接触, 从而实现高记录密度和高传输速率。 至少一个具有N(N是2或更大的整数)的写入元件的写入元件至少以一个整体的方式被布置在轨道宽度方向上,并且至少一个多轨读取头具有L(L是等于或大于N的整数) )读取沿着轨道宽度方向排列的元件形成在旋转滚筒上。 多轨写入头在旋转磁鼓的一个旋转期间将信号写入与磁带并行排列的一组N个磁道,并且多轨读取头通过使用L个读取元件中的任一个读取N个信号磁道组。
