摘要： A magnetic head supporting device for supporting a magnetic head for writing information in and/or reproducing recorded information from a flexible magnetic disk. The magnetic head supporting device comprises a holding plate for holding the magnetic head, and a base plate attached to the holding plate and fastened to the carriage of a magnetic disk driving apparatus so that the magnetic head is supported opposite to the magnetic disk loaded on the turn table of the magnetic disk driving apparatus. The holding plate is provided in its upper surface with a positive pressure creating section in its front end to create a positive pressure for floating the magnetic disk, a floating section in its radially opposite sides to float the magnetic disk stably, and a negative pressure creating section in its central area to create a negative pressure for attracting the magnetic disk. The magnetic head is disposed in the negative pressure creating section with its extremity slightly penetrating a plane including the floating section.

摘要： A write protect switch device accommodated in a disk drive comprises an arm whose one end is supported by a frame of the disk drive, and a rotatable cam member supported by the other end of the arm, whose abutting end slides on a casing of a disk cartridge, the cam member displacing the other end of the arm in the direction of separating from the frame at the time of insertion of the disk cartridge; fitting into a write protect notch of the casing to displace the arm in the direction of approaching the frame when the abutting end arrives at the position of the notch; turning in the ejection direction of the disk cartridge with the arm kept close to the frame at the time of ejection; and after ejection, returning to the state before insertion of the disk cartridge. The write protect switch device also includes a spring for urging the whole arm inclusive of the cam member toward the frame, another spring for urging the cam member in the direction of rotating the same in the insertion direction of the disk cartridge, and switch means performing its switching action in response to the operation of the arm of approaching and separating from the disk cartridge. The cam member swings about the other end of the arm in response to the insertion/ejection movement of the disk to magnify and convert the amount of recess of the notch into the swing stroke of the arm about its one end.
