1. A computer program product for a system for writing tracks of data on magnetic tape, the system having a processor and a tape head which has at least one writer transducer, wherein the computer program product comprises a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause operations, the operations comprising:
using a writer transducer of the tape head, writing a first linear track of data on the magnetic tape moving in a first linear direction; and
using a writer transducer of the tape head, writing a second linear track of data adjacent to the first linear track on the magnetic tape moving in the first linear direction of tape motion and forming a first erase band as the second linear track of data is being written;
wherein the tape head is rotated at a non-zero angle relative to the first linear direction of tape motion as the second linear track of data is being written, and wherein a trailing edge of the writer transducer of the tape head writing the second linear track of data forms an acute angle with respect to a longitudinal edge of the second linear track as the second linear track is being written.
