Abstract
A servo reproduction apparatus according to the present technology includes: a servo reproduction head. The servo reproduction head includes a first reproduction head portion and a second reproduction head portion. The first reproduction head portion reads a servo pattern recorded on a plurality of first servo bands, which are some of a plurality of servo bands in a magnetic tape including the plurality of servo bands. The second reproduction head portion reads a servo pattern recorded on a plurality of second servo bands, which are others of the plurality of servo bands.
