1. A method of electrodepositing a deposited structure onto a substrate surface while controlling a concentration of a diffusion-controlled species in the deposited structure, the method comprising:
immersing the substrate in an electrolyte solution comprising one or more diffusion-controlled species and one or more non-diffusion-controlled species,
applying current to the substrate immersed in the electrolyte to cause the diffusion-controlled species and the non-diffusion-controlled species to form a deposited material on the substrate surface as the deposited structure having a concentration of the diffusion-controlled species that is affected by a dimension or shape of the deposited structure, and
selecting a current density of the current, and selecting a concentration of the diffusion-controlled species in the electrolyte solution, to cause diffusion-controlled deposition of the diffusion-controlled species and formation of the deposited structure having a varied length, width, or height dimension, and a concentration of the diffusion-controlled species that varies with the varied length, width, or height dimension,
wherein the deposited structure is a component of a magnetic recording head.
