Low level control of HDD head positioning
I want to use an HDD mechanics as a tool for precise positioning. Does Ubguntu have tools to issue hard drive commands like "move head to this position" or "spin 90 degrees" ?

That's not how an HDD controller works so it's not possible.

That kind of fine control can only be achieved by a custom firmware for a hard drive. Some drives don't support "flashing" of the firmware. Seagate provides some tools for updating firmware images. The community has some information on the existing commands in the firmware, but overall drives do not provide that specific of control. The closest you're going to get is basically telling the drive to "sweep" the platter which happens at a known constant rate.
