Abstract
A method and a device for manufacturing a thin film by a vacuum deposition method, and a magnetic recording medium produced thereby are disclosed. A thin film of high quality is mass-produced while introducing reaction gas to a thin film forming section from a nozzle consisting of minute tubes, so that the flow of evaporated atoms is not disturbed by the reaction gas.
