Title: Tape cartridge
Inventor: KIKUCHI SHUICHI
IPC: G11B23/087
Filed: 1994-01-26
Abstract: PURPOSE:To increase the surface hardness of a base plate by coating the surface of the base plate with a protective film layer. CONSTITUTION:The upper and the lower surface of the substrate 21 of a base plate 2 are reinforced by coating them with a protective film layer 22. Thus, for instance, in the case of the base plate 2 of aluminum, it becomes unnecessary to apply anodic oxide coating to the surface by providing the protective film layer 22 in the surface of the substrate 21, thereby, being able to reduce the cost. Also, in the case of the plastic-made base plate 2, the surface hardness is increased, thereby being able to prevent the scratch of the surface and the generation of an abrasion powde. The protective film layer 22 can be easily formed by using a synthetic resin series coating agent. Also, by mixing an antistatic agent into the protective film layer 22, the winding disorder of a magnetic tape 4 due to the charging of static electricity can be prevented.
