Abstract A disk file for storing data is disclosed which comprises two major separable assemblies, an HDA assembly and a disk drive assembly. The HDA assembly is characterized by two separate carriage units each of which function to position a plurality of magnetic transducers in transducing relationship with a different group of magnetic disks which are mounted on a common horizontally disposed disk spindle. The disk drive assembly is characterized by an integral baseplate whose front section is generally U-shaped in cross-sections permitting the lower portion of the HDA assembly which surrounds the magnetic disks to be positioned within the opening defined by the opposed surfaces of the U-shaped front portion. The front portion is open to accommodate the positioning of the HDA assembly on the drive assembly by a horizontal loading motion. The drive portion of the baseplate is provided with a horizontally disposed shelf portion to which the magnetic structure of a voice coil motor is mounted. The annular flux gaps of the voice coil motor are positioned to receive voice coils which may be per- manently associated with the carriage units of the HDA. SA979001 The drive assembly further inclues a motor which is disposed beneath the horizontal shelf portion and which may be coupled to drive the spindle of the HDA assembly. Additionally, an air supply system including a blower which is connected directly to the spindle motor shaft is provided to supply contaminant free air to the HDA assembly. SA979001
