Claims

[Scope of utility model registration request]

A servo information core for reproducing position information of a recording medium provided by overlapping a first magnetic layer on which position information is recorded and a second magnetic layer on which data information is recorded, and data on the recording medium. A data information core for reproducing information, a slider incorporating both of these cores, a first discriminator that receives position and data information from the servo information core and outputs position information, and the data information core. A magnetic head device comprising second discrimination means for receiving position and data information from the magnetic head and outputting data information.
