2-6. ID Block
Each ID block consists of segments of approximately 550 kbytes referred to Records. Therefore, the shortest
ID block length is one Record. This is approximately 42 ms at 4
x speed, 170 ms at normal speed (1x), and
2.7 seconds at 1/16
x speed. Thus, recording at 1/16x speed cannot be stopped within 2.7 seconds.
