Other terms not illustrated on this page ...... and their definitions:
.......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 centered and in complete contact with the groove walls...but rather is violently repelled by the grooves from being in constant contact.
