Abstract: A touch panel includes a light-transmitting cover lens, a sensor portion, and a first adhesive layer. The first adhesive layer bonds the cover lens and the sensor portion to each other. The first adhesive layer has a storage elastic modulus at 90° C. of 68 kPa or more and 200 kPa or less. When a surface of the cover lens, being in contact with the first adhesive layer, is a bonding surface, a water contact angle on the bonding surface of the cover lens is more than 0° and 59° or less.
Abstract: An apparatus according to one embodiment includes a block having multiple skiving edges along a tape bearing surface thereof, and a guide mechanism configured to set a wrap angle of a tape approaching the skiving edge. A drive mechanism is configured to cause the tape to move over the block. The block has no transducer coupled directly thereto. A computer-implemented method according to one embodiment includes causing a magnetic recording tape to pass over a block having a skiving edge at a wrap angle of at least one degree for burnishing the tape, wherein the block has an average hardness of at least about 9 Mohs.

Abstract: Embodiments of the present invention recite a write gap structure for a magnetic recording head. In one embodiment, the write gap structure comprises at least one layer of inert material is disposed proximate to the P2 pole of a magnetic recording head. A layer of magnetic material is disposed between the layer of inert material and the P1 pedestal (P1P) of the magnetic recording head. In embodiments of the present invention, the write gap structure further comprises a second layer of inert material is disposed between the layer of magnetic material and the P1P of the magnetic recording head. In embodiments of the present invention, the write gap structure only overlies a portion of the write gap of the magnetic recording head with reference to the throat height dimension of the write gap.
