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。
