Abstract of the Disclosure A magnetic recording medium having a coating of magnetic particles deposited thereon by electrophoresis. Magnetic particles are encapsulated by dry milling in a thermoplastic binder which is insoluble at ambient or room temperatures and is softenable at temperatures higher than 70°C. A charge director for producing functional sites in the binder is incorporated in the encapsulating polymer during the dry-milling step. The encapsulated mass is comminuted or pulverized and then wet-milled with a major amount of a low-boiling aliphatic hydrocarbon liquid. A suspension is then formed with additional hydrocarbon liquid. Additional charge director may be added, either during the wet-milling step or during the suspension- forming step. The suspension is then used as a bath from which the coating is deposited by electrophoresis. The magnetic particles are oriented by the application of a magnetic field, either during the depositing step or sub- sequent thereto. If subsequent, the binder is heated to soften the same. The final coating is then cured by any appropriate means, such as an electron beam.
