摘要： A system and method for loading a head onto a specified load zone of a disk includes reading positional index information for determining a position of a pre-specified load zone of a disk. When to load a head is determined based on the positional index information so that the head will load onto the load zone, the load zone having an arc of less than 360 degrees. The head is loaded from a ramp onto the load zone at the proper time.

摘要： In a magnetic disk apparatus, the spindle motor is provided with a hole that penetrates the hub in the axial direction thereof. The hole permits fluid pressure on the outside and inside of the hub to become balanced, reducing the axial fluid force caused by the rotation of the spindle motor. The apparatus further includes a bearing provided with a groove for dynamic pressure generation and a magnetic lubrication fluid which, in combination with a permanent magnet, prevents oil leakage and scattering.

摘要： A magnetic head slider has a magnetic head mounting surface holding a magnetic head, to be kept closest to a magnetic disk when the magnetic head slider is in operation, a slider rail surface contiguous with a surface, on the side of an air inlet end, and opposite sides of a portion, near an air outlet end, of the magnetic head and extending near to the air outlet end, a step bearing surface formed at least on the side of the air inlet end of the slider rail surface, and a negative-pressure groove formed so as to surround the step bearing surface. The magnetic head mounting surface is typically formed on an alumina protective film protecting the magnetic head. The variation of the flying height of the magnetic head slider with respect to a rolling direction is reduced and a proximity ability to approach the magnetic disk is improved.
