Abstract:
1. A magnetic spacing control method for a magnetic head, which controls the magnetic spacing with respect to a magnetic disk of a magnetic head in which a write element and a read element are separated, the magnetic spacing control method comprising the steps of: continuously supplying power value to a heat generating element of said magnetic head to compensate for scattering; supplying power equal to the sum of said first power value and a second power value, to a heat generating element of said magnetic head at the time of read operation by said read element; driving said write element using a write power, at the time of writing by said write element of said magnetic head while supplying said power equal to said first power value, to aid heat generating element; and supplying to said heat generating element a power having a value which is greater than said first power value, and less than sum of said first power value and said second power value when said magnetic head seeks a target track on said magnetic disk.
