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.
摘要翻译：本发明的信息记录装置包括N个伺服磁头。分别从伺服磁头输出的伺服信号由延迟电路延迟使得伺服信号的波形的峰值相互重合。延迟的伺服信号由加法器相加。因此，伺服信号的输出电平可以增加N次，并且伺服信号的S / N比也可以增加√N倍。结果，PES的精度提高，离轨量可以减少。因此，即使磁带中的磁性层具有小的厚度，也可以防止伺服信号的输出电平和S / N比的下降。

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.
