Gas introduction pipe and magnetic recording medium production method using the pipe

摘要

The present invention provides a gas introduction pipe in which the least component is replaced when deformation or damage is caused and a magnetic recording medium production method using this gas introduction pipe. The gas introduction pipe according to the present invention includes: a gas supply pipe 20 for supplying a gas; a main body 22, 23 connected to the gas supply pipe and having a gas flow passage 21 for flowing of a gas supplied from the gas supply pipe; and a blowoff block 25 arranged at the opposite side of the main body 22, 23 not having the gas supply pipe and having a blowoff opening 27 exposed outward for blowing off the gas outside. The blowoff block 25 is held so as to be sandwiched by the main body 22, 23 and can be detached and attached from/to the main body 22, 23.
