Title:
Magnetic head and manufacturing method
Document Type and Number:
Japanese Patent JP6362309
Kind Code:
B2
Abstract:
An near-field light device (100) is provided with: a first electrode layer (123) having a protruding portion (123a); a second electrode layer (121); and a light emitting layer (122), the protruding portion protrudes along a predetermined direction (Y axis direction) to be capable of extracting energy which is caused by emission of light at the light emitting layer, the predetermined direction intersects with a laminated direction (X axis direction) of the near-field light device, an edge surface of at least one portion of the projection portion is located at more outward side in the optical device than an edge surface of the second electrode layer is.
