Title:
METHOD FOR RECORDING AND REPRODUCING MUSIC PCM DATA RECORDED ON MAGNETIC TAPE TOGETHER WITH TIME CODE ON RANDOM ACCESS STORAGE MEDIUM AND TIME CODE RESTORING METHOD
Document Type and Number:
Japanese Patent JP3439708
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To manage source music PCM data and copy music PCM data with the same time base as a reference even when signals with analog reproducing of the source music PCM data recorded on a magnetic tape together with a time code are sampled for each unknown sampling cycle by a computer and stored on a random access recording medium as copy music PCM data.
SOLUTION: The signals with the analog output of the time code and source music PCM data recorded on the magnetic tape are sampled by the computer and recorded on the random access storage medium as copy music PCM data, time codes Ta and Tb of two sampling time points A and B are stored and a number (n) of times of sampling from the time point A to the time point B, a time difference ΔT from the time code Tb and a sampling cycle (ΔT÷n) obtained from ΔT and (n) are stored.
