Abstract:
A system for storing information comprises a media including a ferroelectric layer, a tip arrangeable in electrically communicative proximity to the media, and circuitry to detect a polarization signal having a radio frequency. The polarization signal corresponds to changes in polarization of domains of the ferroelectric layer at a relative velocity of movement between the tip and the media, wherein a domain of polarization of the ferroelectric layer is information.
Abstract:
A memory device, including a plurality of nanoscale memory cells (1510, 1512) created by applying pressure to and removing pressure from one or more regions (1510, 1512) of a substance (1502) to change the electrical conductivity of those regions (1510, 1512). An electrically conductive read probe (1514) determines the conductivities of the regions and thereby the information stored in the cells. A write probe (1508) applies pressure to and removes pressure from selected cells to change the electrical conductivity of those cells and thereby store or erase information.

Abstract:
A membrane memory system comprises a substrate of a selected metal, anodized to provide a surface layer of a microporous ceramic matrix membrane having substantially regular vertical pores. The microporous ceramic matrix membrane may be separated from the metal substrate by a barrier layer at the bottom of each pore. Data is recorded on the membrane memory system by ablating the barrier layer at the bottom of selected pores so a pattern of ablated and nonablated pores denote positive and negative binary information bits. A method using a modified electron microscope having a rapid, precision swinging electron beam or a laser beam to insert information into or extract information from the membrane memory system is also disclosed.

The electrostatic data recording method which uses a photosensitive member makes it possible to accomplish two-dimensional data-recording, and to record analog, digital, picture, voice and (0, 1) data, and to realize the application electrostatic data recording cards, etc.
Abstract:
A record carrier (40) of a removable type has an information plane that is provided with a pattern of an electro-magnetic material constituting an array of bit locations (11). The presence or absence of said material at the information plane represents the value of a bit location. The device has an interface surface (32) for cooperating with the information plane. The interface surface is provided with an array of electro-magnetic sensor elements (54,56) that are sensitive to the presence of said electro-magnetic material within a near-field working distance. The record carrier and device system have alignment means (38,41) for positioning the bit locations near the sensor elements within the near-field working distance between a bit location and the corresponding sensor when the record carrier is mounted in the device.
