| titleOfInvention | Method for measuring characteristics of magnetic disk media |
| abstract | [PROBLEMS] To accurately measure dimensional deformation characteristics such as a thermal expansion coefficient, a humidity expansion coefficient, and a thermal shrinkage coefficient of a flexible and high recording density magnetic disk medium. A magnetic head in which a servo signal recorded on a track of a magnetic disk medium (10) is fixed in a radial position. In step 16, the dimensional deformation of the magnetic disk medium 10 is measured from the deviation of the track position of the read servo signal. A magnetic disk medium having excellent dimensional stability can be obtained by defining the third or higher order component of the measured deformation rate of the magnetic disk medium after being stored in a predetermined environment to 0.01% or less. |
