Abstract
A multi-track servo recording head includes a multi-tip write core for simultaneously writing a plurality of tracking signals on magnetic storage media. The magnetic recording head may include an optical edge sensor and a magnetic edge sensor for sensing the position of the recording head relative to the edge of the storage media. Additionally, a read core is provided to detect the longitudinal position of the storage media relative to the recording head during media transport.
