A cylinder. Each track on each platter can be thought of as being a ring, thus if you isolated the same track upon each platter you'd have a stack of imaginary rings which would therefore form an imaginary cylinder.
In Great Britian, when track is being laided, there is a track machine used to "tamper" the track so they are straight and parallel to each other.
Two toy electric trains running on the same track are connected in parallel because they both get energized from DC impressed across the two rails they ride on.
If you have two magnets they each have a north and south pole. The opposite poles will attract and the same poles will repel. Maglev trains create magnet fields on the track bed and the train of the same polarity. By controlling the generating of the fields you can hold up the train and propel it forward. Since the train is not actually touching a track there is no appreciable friction except that caused by the surrounding air. In a vacuum you would have no friction.
the difference is that in a shuttle relay, you run back and for(e.g. you run 100m to the next person and they run back to where you started, where the next person is waiting e.t.c.). A circular relay is around a track e.g. a 400m track you each run 100m going round the track. hope this has helped.
For a series circuit... Each bulb has different impedance (ohms) resulting in a different voltage drop across each. Remember Kirchoff's Current Law: The current at each point in a series circuit is the same. That same current, multiplied by the different voltage drops results in different powers (watts = amps * volts) for each bulb. For a parallel circuit. Again, each bulb still has different impedance. This time, the voltage drop is the same (Kirchoff's Voltage Law) but the current in each bulb is different. Same situation - different power in each bulb.
No. of Cylinders = No. of Tracks on each platter multiply by 2 for both sides since each platter stores information on both sides.

On a single platter this is called a track, on a stack of platters (or a double sided platter) the stack of tracks is called a cylinder.

Each side, or surface, of one hard drive platter is called a head. Windows Vista technology that supports a hybrid drive is called ready drive.
The Vertical position of all a drive's read/write heads over their corresponding platter on a specific track, forming a vertical cylinder.
