ABSTRACT:
An improved helical read/write head is disclosed having a cross-cut groove disposed on the lead sloping surface thereof to improve reliability. The cross-cut groove is positioned between the magnetic gap of the helica head and an initial head/tape interface region of the head and is preferably oriented perpendicular to the longitudinal axis/direction of travel of the tape. The cross-cut groove may be particularly positioned to accommodate and dampen tape disruption attendant to initiating the helical head/tape interface.
