Abstract:
A magnetic disk device comprising:a magnetic disk for recording information; a spindle motor for driving the magnetic disk for rotation; a magnetic head for writing information to and reading information from the magnetic disk; a carriage arm supporting the magnetic head; a voice coil motor for moving the carriage arm; a loading/unloading mechanism for retracting the carriage arm from a position on the magnetic disk; a shroud forming a peripheral wall; and a structure forming an air passage extending through a clearance between the voice coil motor and the shroud between a position on an upper side of the carriage arm with respect to a direction of rotation of the magnetic disk and a position on a lower side of the carriage arm with respect to the direction of rotation of the magnetic disk; wherein one end of the air passage is located on a line passing the center of the magnetic disk and at an angle in the range of 10Â° to 30Â° about the center of the magnetic disk measured in the rotating direction of the magnetic disk from a line passing the loading/unloading mechanism and the center of the magnetic disk.
