A station for writing servo track and clock information onto a hard disk drive assembly (HDA) automatically positions and accesses a pallet assembly, including the HDA, in accordance with computerized instructions. A Winchester-type HDA is positioned on the pallet assembly, which in turn is positioned upon a carriage assembly. An automatic, computer-controlled sequence begins which draws the carriage assembly into the station, connects the HDA electronically with the station, and then causes a platten assembly to lift the pallet assembly (with the HDA) into engagement with a top plate assembly. The top plate assembly engages the HDA in a manner wherein the positioning of the HDA actuator assembly is accurately controlled relative to the hard disks located therein. After the hard disks are brought to operational speed utilizing a spindle motor built into the HDA, a clock head assembly positions a clock head to write clock data onto the upper surface of a selected hard disk. A positioner assembly, through an arm assembly, then precisely moves the HDA actuator assembly to erase a face of a hard disk, and then write servo data onto that face utilizing the read/write head of the HDA actuator assembly itself. After the servo data has been applied, the pallet assembly is lowered by the platten assembly, and then withdrawn by the carriage assembly for removal. To assist in disconnecting the HDA from the pallet assembly, ejectors are provided adjacent to a read/write flex connector and to a spindle motor connector on the pallet assembly.
