An apparatus includes a plurality of magnetic read/write heads, a system controller and a switching network. Each of the magnetic read/write heads includes a read sensor element configured to perform a read operation and a write element configured to perform a write operation. The switching network is coupled between the plurality of magnetic read/write heads and the controller. Further, the switching network is configured to substantially simultaneously select elements from at least two of the plurality of magnetic read/write heads in response to a command from the controller such that the operations of the selected elements are performed substantially simultaneously to establish a manufacturing parameter of a disk drive. 本申请公开了用于减少硬盘驱动器制造测试时间的装置和方法。该装置包括多个磁性读/写头、系统控制器和切换网络。每个磁性读/写头包括配置成执行读操作的读传感器元件和配置成执行写操作的写元件。切换网络被耦合在多个磁性读/写头和控制器之间。进步，切换网络被配置成响应于来自控制器的命令从多个磁性读/写头中的至少两个中基本上同时地选择元件以使得基本上同时地执行所选择的元件的操作以建立磁盘驱动器的制造参数。
