| 英文摘要 | 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). |
