    • A magnetic tape driving apparatus includes a magnetic head 2, a temperature/humidity sensor 4, a Peltier element 11, and a controller 15. The temperature/humidity sensor 4 that detects the temperature and humidity of the magnetic head 2 or in the vicinity thereof. The Peltier element 11 that cools the magnetic head 2 and in the vicinity thereof based on detection results of the temperature/humidity sensor 4. The controller 15 that controls the Peltier element 11 based on the temperature and humidity information obtained by the temperature/humidity sensor 4. The controller 15 controls the Peltier element 11 so as to decrease the temperature of the magnetic head 2 and in the vicinity thereof when the humidity of the magnetic head 2 or in the vicinity thereof that the temperature/humidity sensor 4 detects is less than a predetermined value. By adopting this sort of configuration, it is possible to suppress an increase in error rate even in a low humidity environment.

    • There are provide a silicate-based phosphor excellent in emission intensity and a manufacturing method of the same. A manufacturing method of a silicate-based phosphor is characterized by: introducing in a vessel raw material powders having a compound containing light-emitting ions selected from at least one of Eu, Ce, Mn, and Tb; and firing the raw material powders while supplying SiOx (0.5≦x≦1.9, preferably, 0.8≦x≦1.2) in a gas phase. The raw material powders preferably further contains at least one of an alkali metal compound, an alkaline-earth metal compound, a magnesium compound, and a rare-earth compound. The silicate-based phosphor is preferably M2SiO4:Eu2+ (wherein M is one or more selected from a group consisting of Ca, Sr and Ba). The firing is preferably performed by supplying the SiOx to the raw material powders in a gas atmosphere at a temperature of 1200 to 1700° C. and subjecting the raw material powders to a gas-solid phase reaction at a temperature of 700 to 1700° C.
