Abstract
Abstract A recording media playing apparatus including tonal response control circuit configured to control the tone of reproduced sounds, by controlling signal levels of frequency components in a plurality of frequency bands, which are set to divide the frequency range of audio signals read out from the recording media, to designated variation ratios. The apparatus further comprises a memory device, a memory control device for storing, in response to a reproducing-tone memorizing command, data representing the variation ratios in the memory device correspondingly to identification information of each of the recording media, the data representing the variation ratios being stored as tone data, and a tonal response setting device for reading out the tone data using the identification information, the tone data corresponding to a recording medium to be played, and subsequently supplying the variation ratios represented by the tone data to the tonal response control circuit, thereby setting the tone of the reproduced sound. With this arrangement, the tonal response of the apparatus can be set automatically according to the type of music selections to be played.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
264 words
An apparatus for playing recording media carrying audio signals, comprising: a storing part for simultaneously storing a plurality of recording medium of a similar shape, wherein each recording medium is stored in separate positions within the storing part; a tone response control means for controlling the tone of sounds reproduced from said audio signals, by controlling signal levels of frequency components in a plurality of frequency bands, which are set to divide the frequency range of said audio signals, to designated variation ratios; a memory means; a command means for generating a reproducing-tone memorizing command and said variation ratios of said signal levels; a memory control means for storing, in response to said reproducing-tone memorizing command, data representing said variation ratios in said memory means corresponding to identification information of each of said recording media, said data representing said variation ratios being stored as tone data sets, wherein each of said data sets is associated with a unique identification code and each of said identification codes is associated with one of said separate storing positions; and a tone response setting means for reading out said tone data sets dependent upon which identification code is selected, said selected identification code corresponding to a selected storing position of a selected recording medium to be played, and subsequently supplying said variation ratios represented by said read out tone data set to said tone response control means, thereby setting the tone of the reproduced sound, wherein said tone response setting means automatically changes the readout tone data to correspond with an automatic change of the selected storing position.
Claim 2
Independent Claim
264 words
An apparatus for playing recording media carrying audio signals, comprising: a storing part for simultaneously storing a plurality of recording medium of a similar shape, wherein each recording medium is stored in separate positions within the storing part; a tone response control means for controlling the tone of sounds reproduced from said audio signals, by controlling signal levels of frequency components in a plurality of frequency bands, which are set to divide the frequency range of said audio signals, to designated variation ratios; a memory means; a command means for generating a reproducing-tone memorizing command and said variation ratios of said signal levels; a memory control means for storing, in response to said reproducing-tone memorizing command, data representing said variation ratios in said memory means corresponding to identification information of each of said recording media, said data representing said variation ratios being stored as tone data sets, wherein each of said data sets is associated with a unique identification code and each of said identification codes is associated with one of said separate storing positions; and a tone response setting means for reading out said tone data sets dependent upon which identification code is selected, said selected identification code corresponding to a selected storing position of a selected recording medium to be played, and subsequently supplying said variation ratios represented by said read out tone data set to said tone response control means, thereby setting the tone of the reproduced sound, wherein said tone response setting means automatically changes the readout tone data to correspond with an automatic change of the selected storing position.
Claim 3
Dependent Claim
38 words
The apparatus of claim 1, further comprising preprogram means for recording the order in which said storing positions are to be selected, wherein all of recording media stored in said storing positions may be played without manual interference.
Claim 4
Dependent Claim
39 words
The apparatus of claim 1, further comprising memory means for storing a volume setting corresponding to each of said identification codes, wherein the volume setting is automatically changed to correspond with an automatic change of the selected storing position.
Claim 5
Dependent Claim
15 words
The apparatus of claim 1, wherein said recording media are compact disk or laser disk.
