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.
