Abstract

A scanner-based storage system employs a head mounted on a scanner which oscillates over the moving media. The head moves in an approximately sinusoidal path relative to the media at a high frequency, time-multiplexing the read/write signals of several tracks. The resulting multi-channel readback can yield higher data rates over a conventional system with a head that moves linearly relative to the media. Scanner-based storage systems are not commercially available at present. We are envisioning a system that uses an opto-electronic scanner, developed at CMU, in which the deflection of a laser beam is controlled by an input voltage. Since no mechanical motion is involved, this scanner has a high bandwidth which makes it well suited to our application.
