Abstract:
A large-capacity magnetic disk drive comprising:a head main body moving forward and backward along tracks on a magnetic data recording medium; a pair of vertically arranged read/write heads flexibly supported at said head main body, each of said pair of read/write heads flexibly contacting one of two magnetic data recording faces of said magnetic data recording medium with a predetermined head load pressure; a chucking motor for rotating said magnetic data recording medium at a predetermined number of revolutions for one of a high-density magnetic recording medium and for one of a low-density magnetic recording medium by changing the rotation speed of said magnetic data recording medium; and head load pressure adjustment means for adjusting a head load pressure for said pair of read/write heads facing said magnetic data recording faces of said magnetic data recording medium in consonance with one of the requirements for rotation speed of a high-density magnetic data recording medium and a low-density magnetic data recording medium respectively.
