摘要：
The carriage assembly (22) of this invention includes an oval coil (34) whose shape is maintained by a rectangular bobbin (361 which is passed through the open sides of the rectangular carriage frame (24,26,28,30) and fastened inside the carriage frame so that the ends of the coil protrude from the carriage Frame and define symmetrical semi-cylindrical openings on either side of the carriage for cooperation with the magnetic pole pieces (50,52) of the voice coil motor. The transducers are mounted to arms (84) which fit into precision machined sIots (731 in a head mounting block (70) mounted on the front of the rectangular carriage. The connector cable to the transducers is a printed circuit cable (PCC) that passes directly through the hottom portion of the carriage and lies flat along the path of travel of the carriage between the voice coil motor segments which define the movement of the carriage. A support bracket (60) mounted to the rear of the path of travel of the carriage supports a portion (661 of the PCC and causes it to loop back upon itself as the carriage (22) moves toward the rear of the path of travel. The rear of the carriage is open (67), so that the upper portion of the folded PCC cable loop reaches into the carriage as the carriage reaches the rear of its path of travel, minimizing the space the carriage/PCC assembly will occupy.
摘要（中）：
本发明的托架组件（22）包括椭圆形的线圈（34），其形状由矩形线轴（361）保持，该矩形线轴（361）穿过矩形托架框架（24,26,28,30）的开口侧并固定在 托架框架使得线圈的端部从托架框架突出并且在托架的任一侧上限定对称的半圆柱形开口，用于与音圈马达的磁极片（50,52）配合，换能器安装 适用于安装在矩形滑架前部的头部安装座（70）中的精密加工刀头（731）的臂（84），连接器到传感器的连接器电缆是直接穿过热敏元件的印刷电路电缆（PCC） 滑架的一部分，并且沿着滑架的行进路线平坦地布置在限定滑架运动的音圈马达部分之间，支撑托架（60）安装在托架支撑件的行进路径的后部 是PCC的一部分（661），并随着滑架（22）向行进路径的后方移动，使其回到自身。 滑架后部打开（67），使得折叠的PCC电缆环的上部当滑架到达其行进路径的后部时到达滑架，从而最小化滑架/ PCC组件将占用的空间。
