Abstract: A base plate strip is formed with an extension which is forwardly extending from an electrical contact barrel. A groove is provided in the extension such that the groove is extending across a fore open end of the electrical contact barrel. A fore end extended piece of a resilient contact tongue strip overlies the extension of the base plate strip. The resilient contact tongue strip is cut together with the base plate strip along the fore open end of said electrical contact barrel. This defines a stepped surface in the base plate at the open periphery of the electrical contact barrel and defines an engagement end piece at the fore end of the resilient contact tongue. The engagement end piece engages with the stepped surface to prevent the resilient contact tongue from moving in the insertion direction of an associated pin terminal.

Abstract: An information recording and reproduction apparatus for a magneto-optical medium includes a synchronizing signal generation circuit for generating a synchronizing signal to provide a pulsed laser beam at the time of reproduction according to an internal clock obtained from a reproduction signal. The laser beam is driven on/off according to the synchronizing signal at the time of reproduction to have the laser spot on the signal plane prevented from being enlarged, so that the reproducible domain is smaller than the domain of when a laser beam is continuously emitted. In reproduction, an optical superresolution method is applied simultaneous to provision of a pulsed laser beam to allow reproduction of higher density. An external synchronizing signal generation circuit for generating an external synchronizing signal according to a wobble on a surface of a recording medium can be used instead of a synchronizing signal generation circuit according to an internal clock.
