Steppers step, they are used to move the head from one track to the next
but not in between, so if you want smoothness of motion, the gear motor
that ejects the disk (either floppy or cd) is a better choice. You can
control it using the arduino's pwm pins and an h-bridge like the
mshield. Or the L298 chip is easy to set up and inexpensive, will drive
