The size of the gaps between railway sections decreases on a hot day. This is due to thermal expansion.

What is the difference between a disk sector and a track sector?
A magnetic disk is organized with circles called tracks. These tracks (think of the race track around a field) are the path followed by the magnetic head when reading and writing the signal. The data is organized into short sections, called sectors. This is just a convenient size of data, rather like a page is a convenient size within a book. When you read or write data, you do not need to follow the whole track as it spins, just as many sectors as contained the data you are interested in. On the most modern disks, each track holds a megabyte, more or less, and each sector is typically 4096 bytes. The whole disk may have hundreds of thousands of tracks.
