A magnetic tape recording system which achieves very high track densities through utilization of a recording method and apparatus. A magnetic head is described in which the read head gaps are parallel to but laterally offset from the write head gaps. A head assembly is further provided in which the magnetic head is mounted on a rotary motor for aligning the head for writing and reading tracks at different azimuth angles, as well as a stepping motor and linear actuator for stepping the head between tracks. Also, a servo tracking method and apparatus is presented in which writing and reading take place under servo control. This servo allows alignment of the write head gap during writing, and the read head gap during reading, through observation of low frequency servo data blocks dynamically imbedded amidst adjacent track data. The utilization of this servo minimizes tracking error due to lateral tape motion.
