The bias field keeps the domains from becoming random. It is interesting that I was reading about making newer versions of bubble like memory with thin films. They are expecting something like 10 times the data density that current spinning media can have and faster access with no moving parts.

All will be lost if you do. Is my understanding correct that removing the entire 7110 module as a unit (whether socketed or soldered in) should be somewhat safe, but any attempt to disassemble the module would likely disturb the bias field and destroy the data? -- Mark J.
