Claim 7

A method of controlling a plurality of magnetic discs for processing a composite picture image, wherein each of said discs has first and second recording surfaces, each of said, surfaces has a plurality of tracks, and each of said tracks has a plurality of positions, and wherein said composite picture image comprises a first picture image, a picture mask, and a second picture image, said method comprising the steps of: reading said first picture image and converting said read first picture image into a first picture image signal; storing said first picture image signal at least first and second predetermined positions within a first predetermined track of a first recording surface of a first of said magnetic discs; reading said picture mask and converting said read picture mask into a picture mask signal; storing said picture mask at predetermined mask positions within said first predetermined track of a second recording surface of said first of said magnetic discs, at least one of said mask positions corresponding to at least one of said first and second predetermined positions; reading said second picture image and converting said second picture image into a second picture image signal; storing said second picture image signal at second image predetermined positions other than said predetermined mask positions, said predetermined positions being within said first predetermined track of a first recording surface of a second of said magnetic discs; reading out both sides of said first of said magnetic discs, and said first recording surface of said second of said magnetic discs to produce first, second and third read-out signals, respectively; forming a logical AND product between said first and second read-out signals to produce a sub-composite signal; forming a logical OR product between said sub-composite signal and said third read-out signal to produce a composite signal; and printing said composite picture image in accordance with said composite signal.

Claim 8

A method of controlling a plurality of magnetic discs for processing a composite picture image, wherein each of said discs has first and second recording surfaces, each of said, surfaces has a plurality of tracks, and each of said tracks has a plurality of positions, and wherein said composite picture image comprises a first picture image, a picture mask, and a second picture image, said method comprising the steps of: reading said first picture image and converting said read first picture image into a first picture image signal; storing said first picture image signal at least first and second predetermined positions within a first predetermined track of a first recording surface of a first of said magnetic discs; reading said picture mask and converting said read picture mask into a picture mask signal; storing said picture mask at predetermined mask positions within said first predetermined track of a second recording surface of said first of said magnetic discs, at least one of said mask positions corresponding to at least one of said first and second predetermined positions; reading said second picture image and converting said second picture image into a second picture image signal; storing said second picture image signal at second image predetermined positions other than said predetermined mask positions, said predetermined positions being within said first predetermined track of a first recording surface of a second of said magnetic discs; reading out both sides of said first of said magnetic discs, and said first recording surface of said second of said magnetic discs to produce first, second and third read-out signals, respectively; forming a logical AND product between said first and second read-out signals to produce a sub-composite signal; forming a logical OR product between said sub-composite signal and said third read-out signal to produce a composite signal; and printing said composite picture image in accordance with said composite signal.

Claim 9

An apparatus for controlling a plurality of magnetic discs for processing a picture image wherein each of said discs have first and second recording surfaces each of said recording surfaces have a plurality of tracks, and each of said tracks have a plurality of positions therein, said apparatus comprising: a plurality of magnetic discs; a plurality of magnetic heads for writing into and reading out signals in a predetermined region of said magnetic discs; wherein, two separate signals are sequentially stored at two separate regions of said magnetic discs and then simultaneously, read out and combined to produce a new composite signal; multiplexer code means for setting the positional access between said magnetic heads and said magnetic discs; so that a particular magnetic head can be actuated; writing head selector means for receiving information signals to be written into said magnetic discs; reading head selector means for transmitting information signals read from said magnetic discs; and multiplex code register means for controlling both of said receiving means and said transmitting means as a function of a received control signal.
