Do disk drive heads actually touch the disk surface?

No – the read / write heads within the hard drive literally “fly” on a cushion of air (or an “air bearing”) that is created by the spinning motion of the disks. The distance between a head and the spinning disk is extremely small (less than 1/100th the width of a human hair).
