Thanks for help darkforce1.
My point is that I need to use the PCB and HSA to build media disk characterization; i have nano-stage positioning which is used for moving the sample medium underneath the fixed head and doing write/read pattern bits on the sample.
I plan to use the PCB and HSA and then control read/write on level-7; but after removing the media of the drive, it cannot go to any levels due to it need to load data from SA.
If you know how to copy SA and load it manually to the RAM of PCB. Please help me..
-Thanks in advance & best regard.
