Abstract

Each device of a family of removable digital media devices may be plugged into a host to permits the host to store data in it or to retrieve data from it. The form factors of the digital media devices and the connector system used by them are compact for minimizing the volume of space occupied in portable devices and for easy storage. Preferably, the digital media devices of the family use serial memory requiring few power and signal lines, so that few electrical contacts are required. For example, a small number of durable contact pads form the contact arrays on the digital media devices, which in conjunction with corresponding contact pads mounted into a suitable socket provide for easy and convenient insertion and removal and for robust and reliable electrical contact over a long insertion lifetime. The digital media devices interface to the host either directly or through adapters.
