Abstract: A method for recording data onto a disc-shaped recording medium having a sector construction such as an optical disc by dividing input data into predetermined lengths, respectively, two-dimensionally arranging the divided data, generating and adding error correction codes to the two-dimensionally arranged data by a predetermined series to thereby form n encoded blocks; changing the data arrangement among the n encoded blocks; and distributing and recording the changed data to each sector on the disc-shaped recording medium.

Abstract: The present invention discloses a method of producing a discharge display device which enables a LaB.sub.6 cathode to be formed by a thick-film printing method. The method of the present invention comprises the steps of applying a paste prepared by mixing LaB.sub.6 powder with alkali glass powder in a proportion of 20-40 wt. % with respect to the LaB.sub.6 powder to a base electrode, burning the paste, and activating the paste by gas discharge with large current after an exhaustion step to form a LaB.sub.6 cathode on the base electrode.

Abstract: A luminescent material is disclosed which has the general formula:Zn.sub.1-x Cd.sub.x S:Ce.sub.y, M.sub.zwherein M is at least one alkali metal selected from Li, Na, K, Rb, and Cs, x is from about 0 to about 0.3, y and z are densities (g-atom/mol Zn.sub.1-x Cd.sub.x S) of Ce and M relative to Zn.sub.1-x Cd.sub.x S, y is from about 7.times.10.sup.-6 to about 1.5.times.10.sup.-2, and z is from about 7.times.10.sup.-6 to about 1.5.times.10.sup.-2.A method for making a luminescent material having the general formula:(ZnCd)S:Ce,Mwherein M is at least one alkali metal selected from Li, Na, K, Rb and Cs is disclosed which comprises the steps of preparing a mixture of (ZnCD)S:Ce compound, and alkali metal compound, heating the mixture under non-oxidizing atmosphere at a temperature between about 900.degree.
