A thermally assisted magnetic recording method includes the following steps. The recording layer of a magnetic recording medium is irradiated with a laser beam to produce a locally heated region. This heated region is moved by causing the recording layer and the laser beam to move relative to each other. To record desired information, a recording magnetic field is applied to the heated region of the recording layer. The laser beam has a cross section elongated in the direction in which the heated region is moved.

An object of the present invention is to prevent the thin film device formed by laser annealing from making, due to overheat, abnormal operations. Firstly, on a glass substrate 101. a heat insulating film, a silicon oxide film and an amorphous silicon film are formed in succession, and the amorphous silicon film is irradiated from above with a laser beam of an excimer laser. After being molten, the amorphous silicon film undergoes recrystallization to form a polycrystalline silicon film. Subsequently, using the polycrystalline silicon film as an active layer, a TFT is formed, and then a plastic substrate is bonded onto the TFT, and finally the glass substrate is peeled off by way of the heat insulating film, whereby a transfer of the TFT is completed. Because the heat insulating film is removed, abnormality caused by overheat at the time of operation is well prevented from occurring.

The invention relates to a heat insulation plate, a battery module and a battery pack. The heat insulation plate comprises a heat insulation frame, a composite heat conduction material layer and a heat shrinkage film. The heat insulation frame is a supporting frame with an opening. The thermal shrinkage film is connected with the opening of the heat insulation frame so as to surround the heat insulation frame to form a containing cavity. The containing cavity is filled with the composite heat conduction material layer, when the temperature is within the normal temperature range, the compositeheat conduction material layer can play a good heat conduction role, and the composite heat conduction material layer and the heat insulation frame form at least one contact interface. When the environment temperature reaches a preset temperature, the thermal shrinkage film deforms and falls off from the opening of the heat insulation frame, the composite heat conduction material layer is changedinto a liquid state in phase, and the composite heat conduction material layer flows out from the opening of the heat insulation frame. At this time, only the heat-insulating frame remains on the heatinsulation plate, and the average heat conductivity coefficient of the heat insulation plate is reduced, thereby suppressing heat propagation.
