A fixed read/write head utilizing Winchester technology

The traditional goal when designing a fixed-head disc is to combine reliability, compactness and low cost. The usual technique of achieving these goals is to use a large slider containing many read/write heads. When recording density is increased, the heads must operate at a lower flying height, and a large slider interferes with the typical disc profile. Data General´s 6063 fixed head disc drive solves this problem and achieves low cost and reliability by using a three-track ferrite slider of the proven Winchester technology. The disc employs a serpentine gimbal spring which results in a compact head assembly that allows each slider the necessary freedom of movement without affecting other sliders in the assembly.
