    摘要: A communication-capable electronic device is provided which includes a metallic housing (122) to accommodate electronic parts of the device, and a communication terminal (90) that makes communications with a communication-cable IC card (110) incorporating an antenna (115). The communication antenna (90) is located such that when the IC card is placed near the housing (122), the antenna (115) built in the IC card (110) faces, at a part thereof, a part of the communication terminal (90) while the rest of the antenna (115) of the IC Card (110) does not face the housing (122). Thus, it is possible to prevent the inductance in the antenna (115) of the IC card (110) from being reduced.

    摘要: A magnetic head, in the form of a MIG head, having a magnetic metal film formed in the vicinity of the magnetic gap, is provided, in which the thickness of the magnetic metal film in a direction perpendicular to the magnetic gap is not less than 1.0 .mu.m and not more than 4.4 .mu.m and the gap length of the magnetic gap is 0.23 .mu.m to 0.32 .mu.m. The magnetic head is improved in recording characteristics in a specified short wavelength range and hence in the playback output so that it may be advantageously employed for a high digital recording format.
