Mine was more like the mechanism of either a TRS-80 drive, or an IBM Tandon
drive. The heads were connected to a horizontal stepper by a thin metal
sheet.

Odd... I've got a number of Disk II's here, and every one has a stepper
motor under the chassis with a disk on the spindle of it above the
chassis. There's a spiral groove in the disk and a little lug on the head assembly that fits into the groove. The stepper motor
turns the disk and
thus moves the heads.
Maybe there are several versions of the Disk II
