rotary to linear converter
(OP)
I need a way to convert rotary motion to linear motion just like a rack and pinion, but it can't be a rack and pinion or a ballscrew. Anybody have any ideas.

I think you need to ask a slightly better question.

hydraulic pump and pistons?
pulley and string?

A lead screw system is another fairly simple option for rotary to linear translation.

How big, how much force, how accurate, is there contamination, is there lubrication, does it need to back-drive or does it need to resist back-driving, does it need to transmit linear force in both directions, etc.

Takes a lot of voltage to get a solenoid up to full current in that kind of time.

Could you use an arragement like the tatoo machines. I know they can recipitate .250. Don't know about your requirement. If applicable you could use the needle as the piston.

If you didn;t need the dwell time you use a cheap PM dc with a larger shaft and an offset crank pin.
We have some production machinery that uses small PM DC motors to provide oscillating movement to a wire.They buy $1.39 motors, original $.39. All I know about them is that they tell me the're are operating on AC. I called the inventor of this system and asked him about your problem. His response was that his design would not work due to speed requirements.

Let me add that voice coils and magnet housings are easy to design and easily built in-house. I say this because purchased voice coil actuators are insanely expensive.
I can supply all the details you might need if you should elect to try this option.

A 2.5-in HD's platter is 0.9 inches across the annulus, which is traversed in no more than 15 ms, so about 0.4 inches in less than 10 ms
