摘要： A flex circuit for a tape drive includes an elongated flexible printed circuit substrate carrying a pattern of electrical circuit interconnections and divided into a read channel portion for direct connection to multiple read and write heads of a tape head array and carrying a plurality of read channel preamplifiers connected to receive and amplify read signals from a plurality of read heads; a write channel portion including an external connection region for enabling signal and power connections to be made with a host circuit module, the write channel portion including a plurality of write channel drivers; and, a dynamic flexing portion separating and interconnecting the read channel portion and the write channel portion, the dynamic flexing portion adjusting in contour as positional adjustments are made to the head array by a head positioning mechanism. As a related aspect, the flex circuit is secured to a head mounting plate which secures the tape head array, thereby forming a stand-alone multi-track tape head module.

摘要： A data-track head-positioning servo system is disclosed. Data tracks are used to provide position and reference information to a straddle servo head and a reference servo head. The reference servo head provides a reference signal against which the servo signal from the straddle servo head is compared to correct for alignment errors. A transducer head having an integral data transducer, the reference servo transducer, and straddle servo transducer in a fixed spacial relationship is disclosed. A method for using the transducer head in a multitrack tape system is also disclosed.
摘要翻译：公开了一种数据轨头定位伺服系统。数据轨道用于向跨越伺服磁头和参考伺服磁头提供位置和参考信息。参考伺服头提供一个参考信号，来自跨骑伺服磁头的伺服信号与之对准，以校正对准误差。公开了一种具有整体数据传感器，参考伺服传感器和固定空间关系的跨骑伺服换能器的换能器头。还公开了一种在多轨磁带系统中使用换能器头的方法。
