Long Track

One of the simplest and most effective Copy Protection schemes used on the Commodore Amiga.

This is where the disk mastering hardware reduces the size of the bit cells, which allows more data to be written on any one track. This is something which cannot be done on an Amiga.

An alternate way of producing a long track is to slow down the disk drive which in practice it has the same effect - the bit cells take less space, so there can be more cells written to the same area.

Writing short tracks uses exactly the same techniques, but obviously using a wider bit cell width rather than shorter.
