The present invention provides unamount head/arm subassemblies and read-write head stack assembly for a disk drive, and a servowriter having the head stack assembly. Each head/arm subassembly is assembled and aligned individually so that multiple head/arm subassemblies can be installed on a mounting block to build the head stack assembly with all heads being properly aligned. In addition, each head/arm subassembly can be disassembled independently, facilitating easy rework on individual defect head.
