Safer re-recording method for protected cards Message #1 Posted by Bruce Cohen on 25 July 2000, 10:38 p.m. There is a much safer and simpler way to re-record on protected magnetic cards. The technique was published in HP Keynotes long ago. All it required was to cut a waste magnetic card with a projecting tab which filled in the notched corner of the card which was to be rewritten. The cut on the waste card is made vertically with a tab projecting to the top left in such a manner that there is no appreciable gap when the two cards are butted together. To use the “re-write” card, simply push the tabbed end into the discharge of the card slot until the card makes contact with pinch roller. Then feed the protected card into the inlet slot normally to overwrite it. The newly written card will push the “re-write” card out of the slot as it is written. HP published this to allow users to correct errors in some of the application packs. I have used this on both the HP 67 and HP 97. I think HP said that it would also work on the HP 65 but I’m not certain. The article was published about 23 years ago and my memory may have faded due to the gradual loss of my natural cranial sun screen fibers over the years.
