Abstract

A magnetic disk tester according to the present invention comprises a first head moving mechanism for fixedly mounting a first certification testing head and a burnishing head perpendicularly of a moving direction thereof and a second head moving mechanism for fixedly mounting a second certification testing head and a glide testing head perpendicularly of a moving direction thereof. The burnishing head and the glide testing head are switched by the first certification testing head and the second certification testing head, respectively, by moving a spindle in an orthogonal direction to the head moving direction.
