Abstract

A posture adjustment method of a magnetic head is provided. A magnetic head initial position adjustment apparatus measures an initial position of the magnetic head and writes the initial position into an adjustment position information shared apparatus. A magnetic head posture adjustment apparatus reads from the adjustment position information shared apparatus, and information of an adjustment amount given to the magnetic head when the magnetic head is moved and adjusted to a final position is written in the adjustment position information shared apparatus. An adjustment position as a current position of the magnetic head is calculated using the initial position information and the adjustment amount information.

Claims (16)

1. A posture adjustment method of a magnetic head of a magnetic recording/reproducing apparatus having a plurality of head moving means capable of suspending the magnetic head from a base plate and moving the magnetic head with respect to the base plate, the method comprising:

moving, by a magnetic head initial position adjustment apparatus, the magnetic head through the head moving means and adjusting a posture of the magnetic head with respect to the base plate to an initial position,

moving, by a magnetic head posture adjustment apparatus, the magnetic head through the head moving means and adjusting the posture of the magnetic head with respect to the base plate to a final position, and

writing, to an adjustment position information shared apparatus, adjustment position information, the adjustment position information being shared by the magnetic head initial position adjustment apparatus and the magnetic head posture adjustment apparatus, wherein:

the step of moving the magnetic head by the magnetic head initial position adjustment apparatus includes:

a position measuring step of measuring the initial position of the magnetic head which was moved and adjusted, and

a position recording step of writing the measured initial position information into the adjustment position information shared apparatus, and

the step of moving the magnetic head by the magnetic head posture adjustment apparatus includes:

an information obtaining step of reading the initial position information from the adjustment position information shared apparatus,

an adjustment amount recording step of writing information of the adjustment amount given to the head moving means by the magnetic head posture adjustment apparatus when the posture of the magnetic head is moved and adjusted to the final position into the adjustment position information shared apparatus, and

a position calculating step of calculating an adjustment position of the magnetic head using the initial position information and the adjustment amount information.

2. The posture adjustment method of the head moving means according to claim 1 , wherein:

the magnetic head is provided on a carriage adjustment plate, the carriage adjustment plate being suspended from the base plate through the plurality of head moving means,

in the magnetic head posture adjustment apparatus, the magnetic head is moved by the plurality of head moving means, and

the method includes:

if the carriage adjustment plate and the base plate come into contact when the magnetic head is moved, moving the carriage adjustment plate in parallel in a direction away from the base plate to move all of the plurality of head moving means by a same amount.
