Abstract: A magnetic disk information storage apparatus comprises a head/disk assembly removably mounted in a housing assembly. The head/disk assembly encloses rotatably mounted disks, and accessing heads mounted for linear movement on a carriage. Fixed to the carriage and therefore part of the subassembly is a linear actuator coil. The linear actuator magnet structure which cooperates with the coil to produce motion of the carriage is located in the housing assembly. Loadings of the subassembly into the housing assembly locates the actuator coil in a magnetic flux gap of the magnet structure.

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 permanently associated with the carriage units of the HDA. The drive assembly further includes 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.
