    • A head is moved in a lateral direction on the boundary between a separation track and a recording track on a recording medium. The separation track isolates the adjacent recording tracks from each other. A variation is detected in the output supplied from the head based on the recording track. Positional information indicating the position of the head is generated based on the variation. The output supplied from the head varies in response to the movement in the lateral direction, namely the elapsed time. The positional information can thus be generated based on the variation in the output. The generated positional information contributes to an accurate positioning in a facilitated manner. Moreover, information required to position the head can be omitted from the recording medium. The processes can be simplified in the production of the recording medium. The operation time can thus be shortened.
    • 头部在记录介质上的分离轨道和记录轨迹之间的边界上沿横向方向移动。 分离轨道将相邻的记录轨道彼此隔离。 在基于记录轨道从头部提供的输出中检测到变化。 基于该变化生成表示头部的位置的位置信息。 从头部输出的输出根据横向的运动,即经过的时间而变化。 因此,可以基于输出的变化来生成位置信息。 所产生的位置信息有助于以便利的方式进行精确的定位。 此外,可以从记录介质中省略定位头部所需的信息。 可以简化记录介质的生产过程。 因此可以缩短操作时间。
