A magnetic disk apparatus includes a plurality of magnetic disks driven to rotate by a spindle motor, arms supporting magnetic heads on the magnetic disks, an actuator for moving the arms on the magnetic disks by a voice coil motor, and a housing which surrounds the magnetic disks, the arms and the actuator. A shroud which arcuately surrounds the magnetic disks along the outer periphery thereof has an opened portion for inserting the arms is formed in a part of the housing. The shroud on an upstream side of the arms relative to airflow generated by the magnetic disks when rotating is provided with an opening having a greater width than that of a gap defined between the shroud and the outer periphery of the magnetic disks. An empty bypass channel is provided which communicates from the opening through a rear side of the voice coil motor to the downstream side of the arms.

A magnetic disc apparatus having a magnetic disc on which information is recorded, a magnetic head and a magnetic head supporting mechanism. The magnetic head supporting mechanism includes a slider having the magnetic head mounted thereon, a load beam having an arm mounting portion and a pivot, and a gimbal having a mounting portion on which the slider is mounted, two flexible finger portions spaced from the load beam and supporting the mounting portion so that the slider is rotatable with respect to the pivot, and a base end portion which is joined to the load beam. The load beam has two openings formed therein in proximity to the pivot which enable viewing of a back surface of the mounting portion which is opposite to a surface of the mounting portion of the gimbal on which the slider is mounted.

A magnetic disc apparatus having a magnetic head supporting mechanism which includes a slider, a load beam having a spring portion and a pivot, and a gimbal having a mounting portion on which the slider is mounted. The gimbal has flexible finger portions spaced from the load beam which support the mounting portion so that the slider is rotatable with respect to the pivot, and a base end portion which is joined to the load beam. The load beam has elongation portions extending with respect to both sides of the pivot and being connected together in a proximity of a tip end portion of the flexible finger portions so as to be spaced from the pivot of the gimbal and for delimiting a window. The pivot is provided on a projection portion of the load beam which projects in the window from a spring portion side of the window.

A magnetic head slider includes a magnetic head for recording/reproducing information from/into a magnetic disk and a slider on which the magnetic head is mounted. The slider has a first positive pressure generating portion provided at an air-inflow side and a positive pressure generating portion surface provided at an air-outflow side. Projections are provided at the air-inflow side respect to the first positive pressure generating portion on a surface which faces the magnetic disk upon read/write operation of the magnetic head slider.

A head support mechanism includes a head to write/read information, and a head support member to support the head. The head support member has parts delimiting an opening at a portion thereof in which opposing parts which delimit the opening in a width direction of the head support member are elastically deformable. Protrusions are formed on edges of the opening, and piezoelectric elements are mounted on the protrusions to enable deforming of the head support member in a direction of positioning of the head.

A magnetic-disc apparatus includes a magnetic disc, a magnetic head, and a magnetic-head supporting mechanism having a suspension which includes a load beam having a spring portion and an end portion with a pivot and a gimbal having a mounting portion for a slider loaded with the magnetic head. The gimbal has two flexible finger portions that are extended along both sides of the mounting portion. One surface of the end portion which is directed toward a surface of the magnetic disc and one surface of the flexible finger portions which opposes the one surface of the end portion are spaced so as to be out of contact with each other in a region of a tip portion of the gimbal except when the mounting portion undergoes rotational movement.

A head support mechanism includes a slider equipped with a magnetic head to read/write information from/to a magnetic disk, a load beam to provide the slider with an appropriate load, the load beam being flexible in a direction substantially perpendicular to the disk, and a microactuator mounting portion equipped with a microactuator. A first actuator fixing portion, which connects the microactuator mounting portion to a carriage, and a second actuator fixing portion on the magnetic head side of the microactuator mounting portion, which connects the microactuator mounting portion to the load beam, are coupled by two arm portions of the microactuator mounting portion. The microactuator is mounted on the microactuator mounting portion so that the microactuator does not come into contact with the microactuator mounting portion between the first actuator fixing portion and the second actuator fixing portion.

Provided is a magnetic disc apparatus comprising a magnetic head for writing and reading data to and from a magnetic disc, a slider for floating up the magnetic head from the magnetic disc on rotation, a suspension having an IC chip mounting surface, for supporting the slider, a positioning mechanism for positioning a magnetic head at a predetermined position, and an IC chip mounted on the IC chip supporting surface of the suspension, wherein the rate of variation in temperature difference between opposite sides of the IC chip mounting position as a center on the IC chip mounting surface is set to be below about 3.5 K/sec. Thereby it is possible to restrain the averaged seek time for the magnetic disc from becoming longer.
