It comprises a mask () having a first, a second and a third action edge (), and a drive means for moving the mask () relative to a substrate () in a uniaxial direction (A) whereby moving the mask at a fixed rate of movement to cause the edges to successively act on an identical substrate region while successively applying different materials thereto forms thin films of three components successively with respective film thickness gradients oriented in three different directions mutually angularly spaced apart by an angle of 120&#xb0; to allow these films to overlap, thereby forming a ternary phase diagrammatic thin film

Masking mechanism for film forming apparatus

A reproducing apparatus is arranged to have a plurality of reproducing modes corresponding to a plurality of recording modes in which recording is performed on a tape-shaped recording medium by allowing the medium to longitudinally travel at one of different speeds and to reproduce information signals recorded in recording tracks which are formed on the tape-shaped recording medium in the direction of crossing the longitudinal direction of the medium by recording the signals at least in one of the recording modes. The apparatus comprises reproducing means for reproducing the information signals by tracing the recording tracks; reproducing mode error signal generating means for generating on the basis of the information signal reproduced by the reproducing means a reproducing mode error signal relative to whether repreduction is being performed in one of the reproducing modes which corresponds to the recording mode employed in recording the information signal on the tape-shaped recording medium; reproducing mode selecting means for selecting one of the plurality of reproducing modes according to the reproducing mode error signal generated by the reproducing mode error signal generating means; and generation characteristic control means for controlling the reproducing mode error signal generating characteristic of the reproducing mode error signal generating means according to the kind of the reproducing mode selected by the reproducing mode selecting means.
