摘要： A flexible waveguide with an adjustable index of refraction. The core layer and/or the cladding layer of a flexible waveguide may include a plurality of nanoparticles having a different index of refraction than the core layer and/or cladding layer. The plurality of nanoparticles may have an index of refraction that is greater than or less than an index of refraction of either the core layer or the cladding layer in order that the overall effective index of refraction of either the core layer or the cladding layer can be adjusted.

摘要： A head slider moveable relative to a storage media having a storage layer is disclosed. The disc head slider comprises a read head formed on the head slider, and comprises a first electrical contact layer adapted to carry a sensor current, a second electrical contact layer adapted to carry the sensor current, a read sensor and a bias magnet. The read sensor is configured to carry the sense current perpendicular to plane. The read sensor also has a top sensor edge, and has a bottom sensor edge aligned with the air-bearing surface to access data in the storage disc. The bias magnet magnetically biases the read sensor. Further, the first and second electrical contact layers are made of a material that does not magnetically shield the read sensor.

摘要： A magnetic stack includes a self-supporting substrate that carries first and second layer(s). The first layer(s) comprise a magnetic write pole, and the second layer(s) comprise a semiconductor laser. At least one of the second layer(s) is monocrystalline and incompatible with epitaxial growth on the substrate. No support substrate other than the self-supporting substrate attaches to the second layer(s). The magnetic stack may include a near field transducer (NFT) disposed to receive light emitted by the laser. A waveguide may transmit light from the laser to the NFT, or the NFT may couple to the laser without an intervening waveguide. The magnetic stack may be configured for heat assisted magnetic recording (HAMR).
