Quote:You can read parts of a track and then stitch them together as the data repeats.
you cant do this reliably on arbitrary data. it only works if you have reliable syncpoints on the track.
Quote:If I understood it correctly, a real weak bit is a bit that is magnetized lightly and has an unstable state so that sometimes it reads as a 0 and sometimes as a 1.
A single revolution will only read it in one way. Or I got the concept wrong?
this is one type of weak bit, another type is created by using invalid GCR sequences (too many consecutive zeros). |
