Title: Recording medium and its reproducing device
Inventor: FURUGUCHI SATORU
IPC: G11B27/10
Filed: 1992-09-16
Abstract: PURPOSE:To clarify a display of recording contents of a recording medium such as a CD, etc., by constituting one display screen out of data for plural standard screens and fine by displaying a standard screen as one display screen after adding of interpolation data. CONSTITUTION:A user's bit or a title of each piece of music written in W is read out by a CD 21 where data is recorded in graphic data by 1/n of its display screen as data of one screen amt. by presearching. The read bits or titles are stored in a unit of one pack in turn into a RAM 36 by a user's bit processing part 35, and afterward, all the titles of individual pieces of music are recorded in a graphic memory 38 via a graphic processing part 37. When the title is displayed, a picture element for composing a graphic standard screen is 192X288 bits, and since its clear display is difficult, plural standard screens are displayed as one display screen by making a changeover to a fine mode to make the picture element a multiple of plurality of the standard screen. Then, when the standard screen is turned into one display screen, interpolation is performed between lines with just previous line data. By this method, the degree of fineness is promoted to make the display clear.
