Abstract: The cassette half molding method molds one of upper and lower halves of the magnetic tape cassette by injection molding with an injection mold in which a gas vent pin for smoothing a flow of molten resin to be introduced in the cavity for molding a transparent or semitransparent window portion provided in the upper half. The cassette half is molded by this molding method. The magnetic tape cassette has a friction sheet interposed either between a pair of take-up hubs and the upper half, or between the pair of take-up hubs and the lower half, or both, and the friction sheet is made of polyethylene-based resin and has a surface electric resistance value in the range of 1×107 &OHgr; to 1×1010 &OHgr;. The magnetic tape cassette has a rib for reducing a resistance when the roller of the detecting member passes through which is provided at a position corresponding to a recess and on a side of the front lid in the top surface of the body case.

Abstract: A plasma-polymerized film is formed by depositing and polymerizing a metal element-containing material forming an electrode and a gaseous polymerizable carbon-containing reactant in a plasma atmosphere. The polymerized film contains the metal element Mt and carbon C in an atomic ratio Mt/(C+Mt) of at least 1/100. The polymerized film is prepared under a condition W/(F.M) of at least 10.sup.8 joule/kg wherein W is a power applied for plasma generation in joule/sec., F is a flow rate of the gaseous reactant, and M is the molecular weight of the gaseous reactant, F.M being expressed in kg/sec. Such a polymerized film is advantageously applied as a coating to a surface of a member which constructs or is disposed in a casing in which a tape or disk-shaped medium is received for travel or rotating motion.

Abstract: A tape cassette, including opposed, mating housing portions enclosing therein two spaced apart spools with a recording tape wound thereon, each housing portion having a recess therein for tape clearance in the event the tape does not wind properly upon the spools, to thus prevent binding of the tape in the cassette, and resiliently yieldable tape deflector plates in each housing portion on opposite sides of the spools of tape to urge the tape to wind accurately upon the spools.
