Method and apparatus for recording block signal

摘要

Digital signals for normal reproduction (play) are recorded over sequential tracks on a magnetic tape at a specific speed by magnetic heads. The digital signals for normal reproduction will be reproduced also at the specific speed. Digital signals for special reproduction (trick play) are recorded intermittently at the specific speed instead of the digital signals for normal reproduction by the magnetic heads on specific locations of the tracks along paths which will be traced on the magnetic tape by the magnetic heads during the special reproduction. The digital signals for special reproduction will be reproduced at speeds different from the specific speed. Subcode blocks are recorded at or near starting edges of the tracks which will be traced by the magnetic heads from the starting edges during the special reproduction. The subcode blocks include at least special reproduction data related to the digital signals for special reproduction. <IMAGE>
