Title: Digital data recording method
Inventor: TAKEUCHI HIROAKI
IPC: G11B20/12
Filed: 1985-06-13
Abstract: PURPOSE:To make the value of digital sum variation on the unit of one track zero by recording a prescribed pattern in an post amplifying part succeeding the last modulated code of a modulated code string obtained by modulating a digital data. CONSTITUTION:The modulation system converts a data constituted of 8-bit to a modulated code constituted of 14-bit. The modulation is executed as refering to the digital-sum-variation (DSV) value at the end of the modulated code immediately preceeding the data to be modulated, and to the polarity at the end of the modulated code when NRZI modulation is executed, the polarity being positive when the end is of H-level and negative when the end is of L-level. The value of the DSV of the modulated-code string at the end of each modulated code is either one of 0, + or -2, and + or -4. According to the value of the DSV and the polarity, one of the bit patterns shown in the figure is recorded in the post amplifying part following the last modulated code. In such way, the DSV is made zero on the unit of one track.
