Abstract: A scalable cloud-based endpoint security system facilitates a security policy on a plurality of endpoints. Configuration data or commands for implementing a security policy are entered via a web browser of an administrative client device and received at a cloud server. An API server generates a message to a queue of a publication/subscription server that publishes the messages from the queue to one or more subscribing communication servers. A communication server sends the message to an endpoint targeted by the message via a persistent connection that the communication server maintains with the endpoint. In response to the message, the endpoint establishes a connection to the API server. The API server then distributes the configuration data or commands to the endpoint.

Abstract: Described here are methods and devices for aligning an optical servo system used with digital storage media. The devices and methods described herein include alignment apparatuses and alignment test targets, and methods of using them to align the light source outputs of an optical servo system. The alignment test target may comprise an alignment test tape. The alignment test tape may be used to generate an output signal indicative of optical servo system alignment, and this signal may be used to align the light source outputs of the optical servo system.

Abstract: A magnetic tape includes a substrate having disposed on opposite sides thereof a magnetic-layered recording surface and a non-recording surface containing a magnetic servo tracking pattern, the non-recording surface including two layers, an outer layer containing inorganic particles and an inner layer containing magnetic particles.
