Patent JP-H10126143-A (JP)
Title: Loop antenna
Inventor: ITO SADAO
IPC: H01Q11/18
Filed: 1996-10-16
Abstract: PROBLEM TO BE SOLVED: To provide a compact, light-weight and inexpensive loop antenna which can improve performance and also can dispense with a dielectric substrate, etc. by arranging the loop-shaped circuits in a row on the same plane and connecting them together. SOLUTION: Rectangular loop antennas of identical shape and size consisting of the metallic wires such as the copper wires, etc., are tandem connected together on the same plane, via the balanced feeder lines which have length D and inter-line distance E. The lengths (A=B) of both exciting elements are set shorter than the wavelength used with the length D set smaller than 1/2 wavelength, so that the matching of impedance is facilitated between the exciting elements and the feeder lines. The loop resonance frequency is stabilized, when the feeder lines are twisted. Thus, it is possible to secure sharp directivity, to improve gain and also to attain a compact, light-weight and inexpensive structure for every loop antenna, by combining plural loops into a single antenna. Furthermore in addition to a rectangular shape, a circular or elliptic shape is also available to the loop antenna.

Title: Magnetic disk
Inventor: SHIBATA MAKOTO
IPC: G11B5/73
Filed: 1990-11-15
Abstract: PURPOSE:To realize highly reliable driving by cutting a considerably shallow groove between recording tracks of a disk substrate. CONSTITUTION:A disk substrate 11 is formed of resin, onto which grooves 12 are embossed concentrically. A magnetic film 15 at a part 13 between the grooves is used as a recording track. Even when recording is executed by an offtracking head 14, the data is not recorded at the grooves 12. Therefore, even if the head 14 offtracks when reading is started, and if the displacement is not larger than the width of the groove 12, only the amplitude of a reproducing signal is reduced and a signal is never erroneously read from an adjacent track. The probability of generation of errors is small. Owing to the presence of the grooves 12, a clear reproducing signal is obtained for a magnetic flux soaking to both edges in the widthwise direction of the head gap. Therefore, highly reliable driving is realized.
