A non-contact old record recording device

Abstract

The invention discloses a non-contact old record recording device which comprises a rotating platform, an electric lead screw guide rail, a microscope, a linear array CCD, a signal processing circuitand a comprehensive processing module. The rotating platform comprises a stepping motor and a horizontal plate, the horizontal plate is used for supporting and placing a to-be-recorded record, and thecentral axis of the placed record is coaxial with the central axis of the horizontal plate; a microscope and a linear array CCD are mounted on a sliding block of the electric lead screw guide rail; the signal processing device converts the signal of the linear array CCD into a digital signal and transmits the digital signal to the comprehensive processing module; during working, the comprehensiveprocessing module controls the rotating platform to rotate at a constant speed and controls the electric lead screw guide rail to move the sliding block to the initial position, the microscope and the linear array CCD are started to start acquisition, and after the rotating platform rotates for a circle, the electric lead screw guide rail is controlled to move to the position of the linear arrayCCD by the comprehensive processing module to start information acquisition of the next position. The problem that an existing record cannot be directly played and needs to be rerecorded is solved.
