IPC: H03H15/00
Filed: 1982-03-18
Abstract: PURPOSE:To obtain an automatic equalizer having high equalization ability of line characteristics at the data reception mode, by reducing the number of effective tap at the initial stage of the initial training, increasing the effective tap number at the other conventional data reception modes and performing stable  and high speed convergence at the initial training. CONSTITUTION:A carrier generator OSC generates a carier shifted by phase theta from that of a received line signal, and a signal B at a lead 14 in orthogonal amplitude modulation by means of a multiplier MLT1 and a filter LPF is demodulated into a base band signal rk. The automatic equalizer AAE is adaptive automatically and equalized to the characteristics of the line receiving the line signal. An output 22 of the AAE is given to a quantizer QZ, where the symbol included in the line signal is decided from an output yk and quantized. The output 22 of the AAE and an output 24 of the QZ are inputted to a subtractor SUB1, which outputs a difference signal -ek between the signal yk of a lead 22 and a signal ak of a lead 24 to a lead 26 and the signal -ek is inputted to the AAE and is used for the convergence of the AAE.

Inventor: SHIMA CHIEMI
IPC: G11B5/73
Filed: 1994-03-15
Abstract: PURPOSE:To obtain good CSS characteristics and gliding characteristics by forming an alloy film on a nonmagnetic substrate in such a manner that the surface energy of the alloy film is lower than the surface energy of the substrate, and then applying fine metal particles having low melting point in a discrete state in the film plane direction on the alloy film. CONSTITUTION:The substrate for a magnetic recording medium consists of nonmagnetic substrate 2, an alloy film 3 having low surface energy formed on the substrate, and metal fine particles 4 having low melting point on the alloy film. As for the alloy film 3 having lower surface energy than that of the nonmagnetic substrate to be used as a disk substrate, a Ti-Cr alloy film is used. When this film is covered with metal having low melting point, the density of growing nuclei is decreased, which increases the distance between fine particles to be formed. To increase the distance between growing nuclei of fine articles, it is preferable that the composition of the Ti-Cr alloy range 5-80at.% and preferably 30-65at.% ratio of Cr/(Ti+Cr). By this method, a rugged pattern according to the roughness of fine particles is formed on the surface of the protective film 3, the CSS characteristics and gliding characteristics are improved.
