Title: Satoshi Koizumi: Innovator in Audio Signal Recording Technology

Introduction

Satoshi Koizumi is a notable inventor based in Tokorozawa, Japan. He has made significant contributions to the field of audio signal recording technology. With a total of 2 patents, his work has advanced the way audio signals are recorded and processed.

Latest Patents

Koizumi's latest patents include an audio signal recording apparatus with an index number signal generating feature. This innovative apparatus allows for the recording of an index number signal that indicates a pause portion before a music piece, enhancing the recording process. The apparatus delays the audio signal by a predetermined time period to produce a delayed audio signal. Upon starting the recording operation, a muting operation is applied to the delayed audio signal, and a resultant signal is recorded on the medium during the predetermined muting period. Additionally, a subcode information signal containing the index number signal is recorded, indicating a number '0'.

Another significant patent by Koizumi is an audio signal recording apparatus with a track number signal generating feature. This invention ensures the accurate detection of the head position of a music piece. The audio signal to be recorded is delayed for a specific time period, and the start time of each music piece is detected by a transition from silence to sound. The track number signal is incremented at a timing that is shorter than the initial delay, ensuring precise tracking of the audio content.
