Abstract
An improved aqueous electrolyte solution suitable as an electrolytic plating bath is disclosed which is capable of giving a magnetic layer of a cobalt-based alloy on a substrate of a magnetic recording medium used in a high-density vertical-mode magnetization. The electrolyte solution characteristically contains, in addition to the conventional salts of cobalt, manganese and nickel, reducing agent and pH buffering and controlling agents, a water-soluble rhenium salt such as ammonium perrhenate in a concentration of 0.002 to 0.015 mole/liter.
