In a hard drive, the read/write heads float on a cushion of air above the platter. This ensures that there is a tiny gap between the heads and the spinning platter, allowing the heads to read and write data without physically touching the surface of the disk.
If you ignore the process of lifting the mass (just holding it when it gets there), they do the same work but if you include the lifting process, the tall person does more work because the mass is elevated to a higher point first.

The glycerol heads in phospholipids are neutral and do not have a positive or negative charge. The charge on a phospholipid molecule is predominantly determined by the phosphate group located on the glycerol backbone.
The hypothesis of the penny drop experiment is that the design of the container, the height from which the penny is dropped, and the amount of water in the container will affect whether the penny lands heads up or heads down.
Heads, or the anatomical structure of the human head, are not something that can be credited to a single inventor. The evolution of the human head can be attributed to natural selection and the process of evolution over millions of years.

In a hard disk the heads fly above the surface on a thin cushion of air, to prevent wear to the disk or heads. Should something cause the heads to touch the moving disk surface it is called a "head crash" and is not all that different from an airplane crash, as the heads quit flying on their cushion of air.
2 per platter
Each platter on a hard drive has 2 heads.Every Additional Platter you can multiply x2Example:1 Platter x 2 = 2 Heads2 Platters x 2 = 4 Heads3 Platters x 2 = 6 Heads4 Platters x 2 = 8 Heads5 Platters x 2 = 10 HeadsETC...At least until some new hard drive Architecture comes into place.
The head(s) in floppy drives make physical contact with the floppy disk surface, while the heads in hard disk drives fly over the hard disk surface on a cushion of air created by the platter rotation speed. All other features of the devices are similar.
Why do you use a cushion to sleep on? Because it's more comfortable =]
It's getting ready to fail. Either the heads are having problems or the platter bearings are failing.
The Vertical position of all a drive's read/write heads over their corresponding platter on a specific track, forming a vertical cylinder.
Parking the HDD (hard disk drive) heads means the recording heads are moved so they are not over the platter's data area. Many hard drives have an auto-park feature where the heads are automatically parked when power to the drive is turned off.
This is easy. Muscle does not float. If the person has body fat the person will float, the more fat the better the person floats. The less fat, the less a person floats.
The building rose high above their heads. He was the manager directly above him.
To prevent the piston from slamming into the heads, a space must be provided to cushion the piston and bring it to a stop before the return stroke.
