Abstract
In order to prevent the staining of magnetic heads of a magnetic recorder in a low humidity environment, a refrigeration device which refrigerates a magnetic tape is positioned so as to engage the magnetic tape prior to the tape engaging the magnetic heads. The refrigeration device comprises either a refrigeration post or a refrigerated semi-closed space and functions to transfer water to the magnetic tape.
Claims25
A magnetic recorder comprising:
- a rotating cylinder having magnetic heads for recording data on and reproducing data from a magnetic tape,
- a tape transport system for transporting the magnetic tape around the rotating cylinder;
- and
- a refrigeration post positioned so as to refrigerate the tape prior to the tape contacting the rotating cylinder;
- said refrigeration post comprising:
- a post member which contacts the magnetic tape;
- a thermoelectric refrigeration element having an endothermic side and an exothermic side, wherein the post member is connected to the endothermic side of the thermoelectric refrigeration element;
- and
- a heat radiation member connected to the exothermic side of the thermoelectric refrigeration element.
