Can you write the bit stream? Like this AA AB 96 96 96 .... 96 96 96 FC
FC on Track 1 without address field and data field. AA AB is the start of
bit stream. FC FC is the end of the bit stream. Try to read all bytes on
Track 1 and use loop to count the number of byte value 96.
Try to write by replacing from 96 to 97 on Track 1.25. 9A on Track
1.50. 9B on Track 1.75 and 9C on Track 2. Did it tell you when you attempt
to read and count the byte values on Track 1, Track 1.25, and Track 1.50.
Did Track 1, Track 1.25, and Track 1.50 report to be 9A? Did Track 1.75
report 9B?
It is evident that Track 1.50 has overwritten 9A to replace 96 and 97 on
Track 1 and Track 1.25 because the arm head is too width. Track 1.75 and
Track 2 are not overwritten.
Did you have done your experiment?
