14. The method according to claim 13 wherein said acquiring a preselected and desired storage track includes deflecting said electron beam from track-to-track according to an address number defined by a digital address code.
13. A method for addressing an electron beam to select and then scan one of a plurality of spaced-apart and elongated analog data storage tracks defined upon the surface of a target, said method including the steps of: acquiring a predetermined and desired one of said plurality of spaced-apart and elongated analog data storage tracks by deflecting said electron beam to sweep along said target from track-to-track in a direction normal to the extended length of each data storage track; producing a track scan enabling signal upon sweeping of the electron beam along said target onto the desired one of said analog data storage tracks; scanning only the selected storage track by deflecting said electron beam along the elongated length of the selected storage track in response to said track scan enabling signal; causing said electron beam to oscillate at a dither frequency to produce a desired track scan width during the scanning of the length of only the selected one of said analog data tracks; and producing a data signal corresponding to the analog data stored on the selected track during scanning thereof by the electron beam.
