A disc drive assembly for a magnetic disc memory unit is presented. The disc drive assembly has a stationary spindle to which a motor stator assembly is fastened by a wedge ring structure. The motor rotor assembly is constituted by a rotary hub mounted around the stator, the hub having a motor magnet mounted therein. A plurality of magnetic discs may be mounted on the exterior of the hub.

Disc drive assembly for magnetic disc memory unit

A tape transport cartridge is presented having a pair of brakes for the drive belt, the brakes being positioned to increase the angle of separation of the drive belt from the magnetic tape. This increased angle of separation results in improved drive of the tape, and the dual brake arrangement also establishes a more nearly constant instantaneous velocity differential for the tape packs, resulting in a lower and more constant tape tension.
