Mistracking:
.......is related to the ability of the stylus to follow the groove path on the record. Poor alignment or a worn stylus will hinder tracking. but sometimes a particular record will have a passage of extreme amplitude that will prove difficult for some cartridges/stylii to accurately track. Then the result is that the stylus does not remain in complete contact within the groove.
