A signal recording device is provided for transmitting recording data signals via a rotary transformer to a rotary drum having a rotary head for recording data so that control data may be transmitted in a shorter time period and resolution along the time axis may be improved. A 1-bit start bit SB and 2-bit mode setting bits PD are followed by 3-bit group bits GP and 3-bit channel bits CL for a single bit mode, by 3-bit group bits GP and an 8-bit bit patterns BP for a multi-bit mode and by a 4-bit channel number DAN and 8-bit data DAD for D/A data. An even parity PE is appended for each of the respective modes. A continuation flag CF is further appended for the single-bit mode and the multi-bit mode.

Signal recording and reproducing device for transmitting and receiving

In a time base corrector for correcting time base fluctuations of signals reproduced from a record medium, on which a plurality of time-compressed component signals occurring within one horizontal period in a predetermined sequential order are recorded in response to a clock signal with a predetermined frequency, a write clock pulse generator used in the time base corrector includes a phase shifter for shifting the phase of an incoming write clock signal, whereby the write clock signal having a frequency different from the predetermined frequency is generated in response to a horizontal synchronizing signal, the start time of each of the plurality of reproduced component signals is detected and the shifting amount of the write clock signal by the phase shifter is switched in accordance with the detected output so as to synchronize the write clock signal with the start time of each of the reproduced component signal.
