In a cartridge type hard disk drive, a pair of yokes with magnets as a magnetic circuit for a voice coil motor are mounted in a cartridge holder separated from a disk cartridge. When the disk cartridge is inserted into the cartridge holder, a movable coil for the voice coil motor is placed in a magnetic field formed by the magnetic circuit in the cartridge holder. In this condition, a drive current is passed through the movable coil, thereby driving a head arm actuator. With this configuration, the disk cartridge in the cartridge type hard disk drive can be reduced in size and weight. In addition, a further cost reduction and resource saving can also be realized.
