Title:
MAGNETIC REPRODUCING DEVICE
Document Type and Number:
Japanese Patent JPH04305875
Kind Code:
A
Abstract:
PURPOSE:To prevent the omission of a time code by interpolatively processing based on a switching pulse signal. CONSTITUTION:A reproducing signal outputted from a magnetic head 6 is demodulated at a signal processing circuit 4 by a video tape recorder 2 and a video signal OS gained is outputted to a display device 12. A signal from the circuit 4 is demodulated, reproduced and outputted to a system control circuit 8 by a marker processing circuit 10. When time code data DA, etc., are outputted, the data DA is interpolatively processed and the omission is prevented by the circuit 8 based on a switching pulse signal SWP synchronized with the rotary cycle of a rotary drum. That is, at a marker signal ma identification data is allocated to the head block of five blocks and data to be recorded is detected based on the identification data.
