FORMATION OF SPACER FOR ELECTROSTATIC RECORDING HEAD

摘要

PURPOSE:To simply obtain a spacer for an electrostatic recording head with a high accuracy by a method in which an auxiliary spacer part is provided at the top of the electrostatic recording head and the spacer is coated with a paint. CONSTITUTION:The recording electrode 2a portion of an electrostatic recording head 2 is covered with an auxiliary material 5 of Teflon tape with a thickness of 25mum. A coating materal of a given viscosity is coated on both sides of the head 2 in the same thickness as the auxiliary material 5 by spraying to form a spacer part 6. Afterwards, the auxiliary material 5 is removed out to obtain a spacer 1. The spacer to regulate the interval with a recording medium can thus be simply obtained with a high accuracy.
