simplified perspective view illustrating the basic elements of a multitransducer disc translating system a disc 10 is driven by a motor 12 at a substantially constant angular velocity an angular position sensing device 14 senses the disc 39 s speed and angular position for communication to a controller 24 the controller 24 is programmed with instructions for formating data locations on the disc 10 an arm 18 is extended or retracted by an actuator arm positioning mechanism 16 in response to an instruction from the controller 24 transducers 20 and 22 attached to said actuator arm 18 are hence positioned at any of a plurality of preselected positions along a radial line 28 shown dotted the translating system as described so far in this embodiment is similar to conventional disc memory systems data is translated to and from specific disc locations under the direction of the controller 24 which coordinates the timing of data translation with the position of a single transducer either 20 or 22 and the angular position of the disc 10 the preferred embodiment differs from conventional disc translating systems in that two or more transducer heads writing alternately are utilized to translate data onto a plurality of heretofore unusable data tracks the use of a controller 24 to instruct a data directing device 26 to select a specific transducer in a repetitive sequence from among a plurality of transducers such as 20 and 22 in a preselected format which is a function of transducer radial position and disc angular position enhances the efficiency with which data locations may be positioned on a disc to better understand the preferred embodiment it is helpful to first become.
