Case 04-4267-U.S. APPLICATION OF PAUL A. DIDDENS GRAY TONE RECORDER ABSTRACT A gray tone recorder uses a selective variation in a recording stylus duty cycle of an electrostatic recording system which recording stylus continues to write at full voltage using a dry toner electrostactically attracted to a recording paper by an electrostatic charge deposited by the recording stylus. The full voltage recording operation produces a high degree of consistency in the gray level density while the duty cycle variation is effective to vary the separation between record segments by producing variable length segments within fixed recording time periods to achieve a gray scale record. The toner is subsequently fixed or bonded to the paper to create a permanent record. Input data codes are compared with a sequence of fixed codes during a writing time period to determine the cut-off point of each write cycle. The system is adaptable for a plural stylii write head by supplying individual stylus write data during each write cycle.
