    摘要: A thermal printing system includes a heating element with an insulation under-layer of optimal thickness. A method for determining the optimal thickness of such insulation under-layer using equations for the transient temperature distribution at the dye donor/image receiver interface is described. These equations account for the printing system parameters which have the most significant impact on the image formation process.

    摘要: A print head applies electrical energy to an electrically resistive and grounded transfer ribbon bearing heat transferable dye, during sliding pressure contact and relative movement between the head and ribbon, for resistive heating of the dye to a transfer temperature for transfer to a receiver to form images of selective pixel size thereon. The head has a row of electrodes with end faces and an electrically non-conductive substrate with an end face, the end faces lying in a contact plane for contact with the ribbon. A groove in the substrate end face separates such end face from the electrode end faces. The width of the groove is sufficient to inhibit heat transfer at the groove from the ribbon to the substrate for controlling the dye amount heated to transfer temperature adjacent the groove during the relative movement and in turn the image pixel size.

    摘要: A bi-directional magnetic head assembly comprises a first write head adjacent to a read head, adjacent to a second write head. The three heads are in-line, so that the tape engages one or the other write head followed by the read head for either direction of tape motion. The central read head has slots on either side of its transducing region for skiving of entrained air and debris from the tape before the tape engages the transducing element of the read head for either direction of tape travel. On the other hand, each write head has only a single slot for skiving entrained air and debris; a slot being located in each write head structure outboard from the write transducing gap. In reading while writing during bi-directional operation, the write head first approached by the tape for a given direction of motion is the active, writing head. Because the slot is on the outboard side of each write head structure, skiving action occurs prior to the tape reaching the active write transducing gap. However, after the tape successively passes over the writing head and read head, it approaches the second, presently inactive write head from the inboard side of the second write head structure. The approach to the head gap from this direction is over a gently curved, unslotted portion of the second write head. Attendantly, there is minimal skiving action, and entrained air causes the tape to fly without substantially contacting the inactive write structure.

    摘要: A print head applies electrical energy to an electrically resistive and grounded transfer ribbon bearing heat transferable dye, during sliding pressure contact and relative movement between the head and ribbon, for resistive heating of the dye for transfer to a receiver to form images thereon. The head has a row of electrodes, an electrically non-conductive substrate and an electrically non-conductive and thermally insulating barrier layer in abutment, with the barrier layer between the electrodes and substrate. The barrier layer has a thermal conductivity at most about one-tenth of that of the substrate and a thickness sufficient to retard heat transfer from the electrodes to the substrate for controlling the temperature of the electrodes.
