Abstract: In response to determining that a first write operation is to be performed on a portion of tape, writing data to a data track with a tape head element spacing at a nominal value. A tape width of one or more tape positions at which data is written is recorded. In another aspect, a tape width value associated with a tape is retrieved. A current tape width value associated with the tape is determined, and the tape head element spacing is set based on a difference between the retrieved tape width value and the determined current tape width value.

Abstract: A magnetic write head with a flux opposing structure for opposing stray flux from an external source. The write head includes a yoke with two poles and a non-magnetic gap formed there between, and functions to write data to a magnetic storage medium. The flux opposing structure is proximate to the first pole and has a separation from an exterior surface of the first pole. A current applied to the secondary coil to create a secondary flux field with an opposite polarity of a first magnetic flux. The secondary flux field opposes the stray flux associated with the primary flux field of the magnetic write head and/or a neighboring magnetic write head.

Abstract: Setting a servo write head spacing for writing servo tracks on a magnetic tape in a manufacturing environment. One or more processors receive one or more environmental condition measurements of the manufacturing environment. The processors determine a spacing for a pair of servo write heads based at least on a nominal spacing for the pair of servo tracks, and a product of a difference between the nominal environmental conditions associated with the nominal spacing and the corresponding environmental condition measurements of the manufacturing environment, and coefficients of expansion for the magnetic tape. Spacing for the pair of servo write heads is set to the determined spacing, such that the spacing of the pair of servo write heads is substantially the nominal spacing when the one or more manufacturing environment environmental condition measurements are the one or more nominal environmental conditions.
