Keywords: Copy Protection on Amigas

In previous articles dealing with disk format questions it was  
mentioned that the Amiga does not use sectors on its tracks, but
writes out entire tracks at a time.  I am new to the Amiga 
scene and was wondering how various copy protection schemes were
implemented.  I know most of the popular methods on the IBM PC
software (e.g. short sectors, 1 sector per track, half-tracking,
spiral tracking, synchronized inter-sector gaps, CRC and parity
errors.)  However, almost all these schemes are based upon sector
orientation.  Does the Amiga employ the same techniques, but on
a track basis?  Enquiring minds want to know!
