example 1

[0098] The following describes what a learner needs to do to learn to record music on a new disc. Fig. 4 is a diagram for explaining the points of manufacturing the optical disc 15, and Fig. 5 is a top view of the manufactured optical disc. The optical disc 15 is fabricated using the disc 15a shown in FIG. 1 .

[0099] Before learning the recording music operation, all the unit code areas of the code setting band portions B1, B2 and B3 of the disk 15a shown in FIG. 4 and made of white paper are originally white. When the learner sees the score of the music "Chouchou (Butterfly)" which he wishes to record, the learner picks out the tones corresponding to the scale in order. Use a water fiber velvet tip dyeing pen to color the unit coding area 17 (b1) black, and the learner is in the first unit coding setting area composed of the unit coding areas 17 (a1), 17 (b1) and 17 (c1) Record the "sol tone" in the form of coding; use a water fiber velvet tip dyeing pen to color the unit...

example 2

[0105] This example relates to a learning tool comprising the optical disc shown in Fig. 5 and the reading device shown in Figs. 6-9b. FIG. 6 is a perspective view showing the entire structure of a reading device for reading coded information of an optical disc by a photoelectric conversion method to output an audio signal. Figure 7a shows a perspective view illustrating the connection of the carousel 8 in the reading device of Figure 6 . Figure 7b shows a front view illustrating a portion of Figure 7a.

[0106] On the optical disk 15 shown in FIG. 5, the tone of the music "Kirakira Boshi (Sparkling Star)" is recorded on the unit code setting area using a combination code of black and white binary signals. When the optical disc 15 is placed on the turntable 8 of the reading device shown in FIG. This operation is described in more detail below.

[0107] FIGS. 8 a to 8 c relate to the connection of the sensor substrate 11 of the reading device shown in FIG. 6 . FIG. 8 a is a...

Abstract

A disc with music recorded in encoded form is placed on the turntable of a CD player and the turntable is rotated by hand. The coded information is detected and decoded by the sensor substrate and the main circuit board, and the tone of the corresponding frequency is output from the speaker. A lot of unit code setting areas are set on the white surface of the optical disc, and a certain unit code area is selected on each unit code setting area to be painted in black, and white and black represent logical values ​​"0" and "1" respectively. "Binary signals, thus combining and encoding the binary signals.

Description

technical field [0001] The present invention relates to optical discs, magnetic discs and learning tools equipped with at least such discs, in particular to learning tools using compact disc players (hereinafter referred to as "CD players"), and more particularly to learning CD playback using CD players A learning tool for the fundamentals of how a device works. Background technique [0002] The CD player system was created more than thirty years ago. The introduction of computer-based methods for digitizing audio signals, as well as advances in semiconductor technology, optics, and plastics technology, facilitated the development of CD player systems. Currently, the CD player system has completely replaced the LP record player system. [0003] Due to the widespread popularity of CD players, the age group of music lovers has greatly expanded, and now even children in elementary school can easily operate CD players to enjoy music. [0004] As an example, a phase-shift opti...
