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.

Abstract: 1,101,214. Photographic developing apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 20, 1966 [Feb. 3, 1965; March 17, 1965], No. 2600/66. Heading G2A. Apparatus 18 for developing photographic film by passing ammonia under pressure across film surface 17 comprises a seal plate 19 having a diffuser plate 16 placed in a cavity therein and a closure platen 22 which presses an inserted film tightly against the seal plate 19. Ammonia under pressure is fed by a valve 32 to a hole 28 in the base of the plate 19 and from there it flows as indicated, forcing the trapped air before it into a reservoir 15. In another embodiment, Figs. 1, 2 (not shown), the trapped air is forced into a reservoir (11) between a metal seal (2) and an elastomer seal (3). In a further embodiment, Figs. 5-7 (not shown), a three way solenoid valve (110) controls the feeding of ammonia from a store to a development cavity (114), and after development, to exhaust the ammonia out of the development platen into an absorber (115). A fluid other than ammonia may be used.

Abstract: A disk storage apparatus includes an interchangeable sealed cartridge, enclosing magnetic disks, accessing magnetic head arm assemblies, a movable carriage to which the head arms are mounted, and a drive spindle on which the disks are seated. For accessing the heads to selected data tracks, coupling means are provided to engage the carriage and head arm assemblies with an external actuator, such as a linear D.C. motor or voice coil motor, disposed in a disk file housing. The file housing includes a drive motor coupled by pulley means, for example, to the enclosed spindle to provide rotary motion to the disks.
