Abstract: A magnetic head assembly, for use in a tape drive wherein a tape is moved past the head assembly in a longitudinal direction and the tape exhibits transverse tape movement correlated with the position of the tape in the longitudinal direction, and wherein a minimum longitudinal distance exists for which the correlation is maintained, has a carrier with first and second gap and coil arrangements disposed on the carrier. The respective gaps in the first and second gap and coil arrangements are disposed on the carrier separated by a spacing which is less than the aforementioned minimum longitudinal distance. If one gap and coil arrangement is used as a write arrangement, and the other gap and coil arrangement is used as a read arrangement for verifying the writing of data by the write arrangement, tracking errors are minimized, or substantially avoided, because the write and read arrangements are so close to each other as to be effectively at the same position in the context of the transverse tape movements.

Abstract translation: 一种用于磁带驱动器的磁头组件，其中磁带沿纵向方向移动经过磁头组件，并且磁带呈现与磁带在纵向方向上的位置相关的横向磁带移动，并且其中存在最小纵向距离 保持相关性，具有载体，其具有第一和第二间隙以及设置在载体上的线圈装置。 第一和第二间隙和线圈装置中的相应间隙设置在载体上，间隔小于上述最小纵向距离。 如果使用一个间隙和线圈布置作为写入布置，并且另一个间隙和线圈布置用作用于通过写入布置来验证数据写入的读取布置，则跟踪误差被最小化或基本上避免，因为写入和 读取布置彼此非常接近，以便在横向带移动的情况下有效地处于相同的位置。
