Inventor: KANEKAWA ICHIRO
IPC: G11B5/455
Filed: 1997-03-17
Abstract: PROBLEM TO BE SOLVED: To shorten the measuring time and simplify a measuring apparatus structure in the apparatus and method for measuring the grinding force of a magnetic storage medium to measure the the grinding force of a magnetic tape which gives influence on the friction of head of a magnetic recording apparatus. SOLUTION: A ball 12 which is fixed to a recess section of a ball holder 13 is placed in contact with one surface of a magnetic tape which is caused to run by an existing VTR, etc. A flat base 14 is provided at the position opposed to the ball 12 at the other surface of the magnetic tape 11. The end section of ball slides while it is pressurized to the running magnetic tape 11 and therefore a part of the ball 12 sliding with the magnetic tape 11 is worn. Amount of wear W of this ball 12 corresponds to the measured value of wear of the magnetic head and a grinding force of the magnetic tape can be obtained by calculating amount of wear W by observing the wearing surface with, for example, an optical microscope. Wearing rate by the sliding is sufficiently high and the measuring time becomes short.
