Abstract: A method of texturing includes the process of enhancing the hydrophilicity on the surface of a substrate for a recording medium. A texture is then formed on the surface of the substrate with an aqueous slurry in which abrasive grains are dispersed. The surface of the substrate is expected to exhibit an enhanced property of wetness to the aqueous slurry. The aqueous slurry easily spreads over and contacts the surface of the substrate even from the initial stage of the process. The abrasive grains in the aqueous slurry are allowed to uniformly spread over the surface of the substrate. Establishment of the texture can be started on the surface of the substrate at an earlier stage of the process. Even with the abrasive grains of a smaller grain size, a fine and uniform texture of a predetermined surface roughness can be established on the surface of the substrate within a shortened period.

Abstract: The invention enables a source speech signal to be coded in an optimal way. An adaptive codebook (Ba) stores a series of signal vectors of a past speech signal. A vector extraction means extracts a signal vector and neighboring vectors adjacent thereto. A high-order long-term prediction synthesis filter produces a long-term predicted speech signal (Sna−1) from the signal vector and its neighboring vectors. A filter coefficients calculation means calculates filter coefficients of the long-term prediction synthesis filter. A perceptual weighting synthesis filter obtains a reproduced coded speech signal (Sna) from the long-term predicted speech signal (Sna−1). An error calculation means calculates the error (En) of the reproduced coded speech signal (Sna) with reference to the speech signal (Sn). A minimum error detection means finds a minimum error point that yields the smallest error among the calculated errors.
