    摘要: A molding die (31,32) for molding a magnetic tape cartridge case in which an electronic part for exchanging a signal with the outside via contacts is incorporated as the need arises is such that a molding die portion for use in molding openings for exposing the contacts of the electronic part is constituted of two kinds of inserts which are alternatively attachable to the molding die (31) proper; and a first insert (33A) is used to form openings for exposing the contacts, whereas a second insert is used to shut the openings for exposing the contacts.

    摘要: The present invention is a biaxially oriented polyester film having a ratio of Young's modulus in the transverse direction to Young's modulus in the machine direction of 1.5 to 3, an average value of refractive indices in the machine direction, in the transverse direction, and in the thickness direction of 1.590 to 1.680, a minor melting peak temperature of 160 to 190°C, and a coefficient of hygroscopic expansion in the transverse direction of 0 to 6 ppm/% RH.
    The present invention provides a biaxially oriented polyester film that, when used as a magnetic recording medium, undergoes little dimensional change due to environmental changes and has excellent storage stability and good slittability, film forming ability, and processing suitability.
