发明名称 FRINGE FIELD COMPENSATION SYSTEM FOR MULTI-TRACK SERVO RECORDING HEAD
摘要 A multi-track servo recording head assembly (80) records a plurality of identical tracks (94) of servor information (90) longitudinally defined within a very high density servo section (86) along a magnetic recording medium (44). The servo recording head assembly includes a write transducer (82) for writing a servo signal, as well as an erase transducer (84) that includes two outer erase elements (96) and at least one inner erase element (98) positioned between the two outer erase elements. Each erase element erases alternating portions of the servo signal to create at least one of the plurality of tracks of servo information in the servo section. The outer erase element and the inner erase element are positioned transversely across the servo section, with the inner erase elements having an erase head width that is less than an erase head width of the outer erase elements. The difference in erase head widths between the inner erase elements and the outer erase elements compensates for a combined fringe field effect (112) that occurs between adjacent erase elements (104-1, 104-2) when creating a very high density multitrack servo section on a longitudinal magnetic recording tape. As a result, even though the erase head widths of the inner and outer erase elements are different, the resulting track width of each of the plurality of tracks of servo information is substantially identical.
