High resolution recorder for magnetic printing

A high resolution rotating head recorder for generating magnetic latent images on magnetic tape for magnetographic printing is described. The device is capable of recording a full 8.5 by 12 inch page with a resolution of up to 1000 dots per inch. It is designed as an experimental tool for investigating the halftone reproduction capability and speed and quality limits of magnetography. A detailed description of the device is given and its operating characteristics are discussed.
