Title: Magnetic recording medium
Inventor: NOCHI KIDAI
IPC: G11B5/706
Filed: 1981-04-20
Abstract: PURPOSE:To prevent blocking phenomenon of a magnetic recording medium at a storage for a long period from generating, by providing a rugged coating layer including plate bodies on the back side of a plastic film having a magnetic substance layer on the front surface. CONSTITUTION:A ferromagnetic thin film 1 is laminated on a surface 3 of a plastic film 2 and a rugged coating layer including plate-shaped particles 7 (e.g., alpha-FeOH, alpha-Fe2O3, ZnO) is provided on a rear surface 5 to obtain an objective magnetic recording medium. Thus, in storing the magnetic recording medium on a reel, the surface 4f of a ferromagnetic thin film 1f is in contact with a rear surface 5e of an adjacent magnetic recording medium 2e, but since the rear surface 5e shows a rugged pattern, the area when the surface 4f and the rear surface 5e are bonded is decreased as a whole, allowing to reduce the production of blocking phenomenon.

Abstract: PURPOSE:To realize the magnetic reproducing device capable of performing its reproducing at a suitable speed for edit work by making the traveling speed of a magnetic tape selectable out of plural speeds by controlling a magnetic tape driving means during the operation of a manual reproducing function. CONSTITUTION:In the case of a manual edit function for performing manually the reproducidng under traveling of the magnetic tape, when an edit key 1a is operated, the reproducing can be performed even by rotating manually a reel wound with the magnetic tape, so that the edit work can freely be carried out.

Abstract: PURPOSE:To allow the detection device to contribute to the stable operation of a system by providing the simple standing wave ratio detection device to the MODEM so as to simply detect the deterioration in an impedance of a transmission line at test or the like at application of power. CONSTITUTION:A standing wave ratio detection means 31 detects a standing wave ratio in a MODEM 30, that is, the standing wave caused by a deviation in a characteristic impedance of a transmission line side from a specified impedance and a deviation in a characteristic impedance of a MODEM side from the specified impedance respectively, and an alarm generating means 32 raises an alarm when the detected standing wave ratio is the specified value or over. The opportunity for detection is dependent on the instruction by operator, for example, at the time of power source ON. Furthermore, since the standing wave ratio detection means 31 in use in this case is formed to detect the standing wave ratio at a frequency used by, e.g. the MODEM 30, the structure is simplified and the mis-matching of the transmission line is simply and properly detected and stable data transmission is ensured.
