Abstract
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.
