Filed: 1998-10-28
Abstract: PURPOSE: A method of mounting the COB(Chip On Board) is provided to prevent its mounting direction from being inversed on a smart card without an inspection of the mounting direction. CONSTITUTION: A smart card to prevent inverse mounting of a COB is made up a COB and the body of a card. The COB is consisted of a PCB(printed circuit board), semiconductor chips, via holes, contact terminals, and a detection part of mounting direction. The PCB has a circuit pattern and no lumbar region on the upper surface. The semiconductor chip is attached to the base side of the PCB and simultaneously its bonding pad is bonded with the circuit pattern by wires. The via hole is electrically connected to the circuit pattern side of having no wire bonding and simultaneously goes through the PCB. The contact terminal contacted to the via hole is formed on the other side of the PCB. The detection part of mounting direction is formed by chamfering one corner or multiple corners among the PCB corners.

Filed: 1997-05-22
Abstract: A method and apparatus for trackwise burst error correction in multitrack storage has an error protective code format that is based on first and second linear block codes each with a plurality of symbols. Of each word pair that consists of one word from either code, and whose words have a pivot symbol in common, the latter words have mutually different cross-track orientations. Each individual symbol forms the pivot symbol of one such word pair. The method first decodes an error-decodable word pair having such pivot symbol in common. The next word pair is minimally shifted with respect to the latter pivot symbol and is then decoded, such shifting being non-uniform as based on the outcome of a most recent decoding. The method then alternates the shifting and decoding steps.
