Magnetic transducer combination with formatting, data, and servo heads

摘要

A combination magnetic transducer head apparatus which can easily achieve initial formatting of data tracks of a rotating magnetic recording medium such as a hard disk without using a specific separate initial formatting system. The apparatus comprises a magnetic head for initial formatting, another magnetic head for servo control and a magnetic recording and playback head all mounted on a head slider. In the apparatus, at least one track is first recorded on a magnetic disk by the magnetic head for initial formatting and then another track is recorded by the magnetic recording and playback head while the first track is scanned by the magnetic head for servo control whereafter such a series of operations are repeated until completion of recording of all tracks required.
