Abstract
An information recording and reproduction device comprises an optical pickup that has an objective lens and records information to a tape-form medium or reproduces information from a tape-form medium using laser light; a tape threading component that allows the tape-form medium to be arranged opposite the objective lens; a controller that detects that the tape-form medium is a cleaning tape; a movement mechanism that operates so as to bring the tape-form medium and the objective lens into contact with each other, in response to the detection by the control unit; and a first drive mechanism that plays out the tape-form medium in a state in which the tape-form medium and the objective lens are in contact with each other. The information recording and reproduction device is capable of cleaning the optical pickup even with a tape-form medium.
