A carriage with a recording head mounted therein is movably supported by a first guide member extending in a direction intersecting with a recording medium transport direction \u201ca\u201d. A selected memory cell is programmed by hot carrier injection. The trench bottom oxide portion of the first oxide can have a thickness greater than a distance within the epitaxial layer from the first trench to the second trench. The door is configured to be assembled with the opening of the housing. There are sensing elements fabricated within the flexible substrate and proximate to the upper surface to detect properties of the body.
