Abstract

Abstract A method for setting a sound recording level by reproducing a signal recorded on a recording disk (1) is provided in which a playing operation and a track jumping operation are alternately performed by a disk playing unit (A). During each playing operation, peak values of the audio signal recorded on the disk (1) are sampled and stored. The sound recording level is set according to an average of the sampled peak values. In addition, where several pieces of music are recorded on the disk, the number of tracks jumped during the track jumping operation may be changed in accordance with the playing time of each of the recorded pieces of music. Also, the number of tracks jumped during the track jumping operation may be changed as the jumping operation progresses toward the outer circumference of the disk.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 99 words
A method for setting a sound recording level by reproducing a signal recorded on a disk (1) using a disk player (A) for playing the recorded disk, and a recorder (B) for recording the signal on a predetermined medium, the method comprising the following steps: alternately performing playing and track jumping operations by a disk player; sampling audio signals recorded on a disk to obtain a sampled value group representing peak values of the audio signals sampled during each of the playing operations; and, setting a sound recording level according to an average value of the sampled value group.
Claim 2
Independent Claim 99 words
A method for setting a sound recording level by reproducing a signal recorded on a disk (1) using a disk player (A) for playing the recorded disk, and a recorder (B) for recording the signal on a predetermined medium, the method comprising the following steps: alternately performing playing and track jumping operations by a disk player; sampling audio signals recorded on a disk to obtain a sampled value group representing peak values of the audio signals sampled during each of the playing operations; and, setting a sound recording level according to an average value of the sampled value group.
Claim 3
Dependent Claim 41 words
A method according to claim 1, wherein a plurality of pieces of music is recorded on the disk and a number of tracks jumped during the jumping operation changes according to a playing time of each of the pieces of music.
Claim 4
Dependent Claim 32 words
A method according to claim 1, wherein a number of tracks jumped during the track jumping operation is reduced as the jumping operation is performed towards the outer circumference of the disk.
Claim 5
Independent Claim 41 words
A method according to any of claims 1 to 3, wherein the setting step comprises: adjusting a gain at an amplifying stage of one of the disk player and the recorder according to the average value of the sampled value group.
Claim 6
Independent Claim 24 words
A method according to any of claims 1 to 4, wherein the disk player (A) and the recorder (B) are integrated into one unit.
Claim 7
Independent Claim 24 words
A method according to any of claims 1 to 4, wherein the disk player (A) and the recorder (B) are provided as separate units.
