ABSTRACT:
A magnetic disk cartridge includes a magnetic disk sheet, a center core which holds the magnetic disk sheet and is provided with a spindle insertion hole at a center portion thereof and with a drive pin insertion cutaway portion spaced from the spindle insertion hole, and a casing which contains therein the magnetic disk sheet and the center core for rotation. The magnetic disk cartridge is loaded in a disk drive system having a rotary support table which magnetically attracts thereagainst the center core, a spindle which is circular in cross-section and is inserted into the spindle insertion hole, and a drive pin which is inserted into the drive pin insertion cutaway portion and is moved radially outward when the rotary support table is rotated. The spindle insertion hole is circular in shape and is adapted to be tightly fitted on the spindle of the disk drive system. The drive pin insertion cutaway portion extends radially outward to a position where the drive pin cannot reach the radially outer wall of the cutaway portion when the drive pin is moved radially outward in response to rotation of the rotary support table.
