摘要： A magnetic tape driving apparatus of the present invention includes a support member for separating a magnetic tape from a magnetic head on at least one of a tape input side and a tape output side of the magnetic head. The support member separates the magnetic tape from the magnetic head at least when a tape driving portion causes the magnetic tape to start running and/or to stop running. With this configuration, the magnetic tape driving apparatus does not suffer from damage to the magnetic head and the magnetic tape when the magnetic tape makes a transition from the stopped state to the running state and vice versa or changes in the running direction.

摘要： The information recording apparatus of the present invention includes N servo heads. Servo signals outputted respectively from the servo heads are delayed by a delay circuit such that the peaks of the waveforms of the servo signals coincide with each other. The delayed servo signals are added up by an adder. Thus, the output level of the servo signal can be increased by N times and the S/N ratio of the servo signal can be also increased by √N times. As a result, the precision of PES improves and the amount of off-track can be reduced. Therefore, even if a magnetic layer in magnetic tape has a small thickness, it is possible to prevent the decline of the output level of the servo signal and the S/N ratio.

摘要： In a recording/reproducing method of a magnetic tape in a tracking servo system, a recording density of each data track is increased while inhibiting occurrence of a recording/reproducing error caused by a size change of a magnetic tape in the width direction. Data tracks are each set to have a smaller track width stepwise as closer to servo tracks (41T-1 to 41T-5 etc.) in the width direction of a magnetic tape 1. With such a setting, the width of the data tracks (A1-41T-1 to A1-41T-5 etc. ) closest to the servo tracks (41T-1 to 41T-5) can be minimized, thereby enabling a significant increase in number of the data tracks. Further, even when the size of the magnetic tape 1 changes in the width direction due to a change in external environment such as a temperature or moisture, to lead to large displacement of the data tracks (A8-41T-1 to A8-41T-5) distant from the servo tracks (41T-1 to 41T-5), the data head (A8) can be readily aligned to face the data tracks (A8-41T-1 to A8-41T-5) in the reproduction by an increased portion of the width size of the data tracks (A8-41T-1 to A8-41T-5), and it is thereby possible to ensure reading of data signals from the data tracks (A8-41T-1 to A8-41T-5) so as to improve reproduction accuracy.

摘要翻译： 在跟踪伺服系统中的磁带的记录/再现方法中，增加每个数据磁道的记录密度，同时抑制由磁带在宽度方向上的尺寸变化引起的记录/再现错误的发生。 数据磁道各自被设置为具有比磁带1的宽度方向更靠近伺服磁道（41T-1至41T-5等）的逐渐减小的轨道宽度。通过这样的设置，数据磁道的宽度 最靠近伺服磁道（41T-1至41T-5）的A1-41T-1至A1-41T-5等）可以最小化，从而可以显着增加数据磁道的数量。 此外，即使当磁带1的尺寸由于诸如温度或湿度等外部环境的变化而在宽度方向上变化时，为了导致数据磁道的大的位移（A8-41T-1至A8-41T- 5）远离伺服磁道（41T-1至41T-5），数据磁头（A8）可以容易地对准数据磁道（A8-41T-1到A8-41T-5） 数据磁道（A8-41T-1〜A8〜41T-5）的宽度尺寸的增加部分，从而可以确保从数据磁道读取数据信号（A8〜41T-1〜A8〜41T- 5），以提高再现精度。
