    摘要: Systems in accordance with the present invention can include a tip contactable with a media, the media including a substrate and a plurality of cells disposed over the substrate, one or more of the cells being electrically isolated from the other of the cells by a material having insulating properties. One or more of the plurality of cells can include a phase change material. The media is either grounded or electrically connected with a voltage source such that when the tip is placed in contact with the media and a voltage is applied to the tip, a current is drawn through the cell over which the tip is arranged. The current is drawn through the isolated cell at least a portion of the phase change material within the cell beneath the tip is heated to a sufficient temperature such that the material become amorphous in structure. The current is then removed from the phase change material, which is quickly cooled to form an amorphous domain having a resistance representing a “1” (or a “0”). In an embodiment, the one or more cells can have a sidewall structure that tapers along the depth of the cell so that the cell has a wider cross-section near where a tip contacts the media and a narrower cross-section near where the cell contacts one of the substrate and an underlayer.

    摘要: Systems in accordance with the present invention can include a tip contactable with a media, the media including a servo pattern, an inhibiting matrix having a plurality of cells disposed within the inhibiting matrix, wherein the servo pattern is defined at least partially by the plurality of cells. A data portion amongst which the servo pattern is disposed can further be defined within the inhibiting matrix. Alternatively, the data portion can include a continuous media. A tip including a conductive contact surface can be positioned in contact or near-contact with the plurality of cells, and a voltage potential can be applied across the media from the tip. A resistance of the at least one cell is then detectable. In an embodiment, the resistance of the at least one cell can be lower than a data indicium within the continuous media or within a patterned media, thereby identifying the cell as a servo mark. In an embodiment the at least one cell can be a read-only cell having a conductive material disposed within the cell. Alternatively, the at least one cell can be a write-once cell including a switchable material. A large current can be driven through the write-one cell to form an effectively permanent servo mark, the servo mark having a resistance smaller than a resistance of an indicium.

    摘要: Provided herein are embodiments for adjusting a built-in bias of a media including a conductive layer and a ferroelectric layer above the conductive layer. In certain embodiments, a voltage signal is applied between the conductive layer of the media and an electrode (provided over at least a portion of the ferroelectric layer) to thereby tune the built-in bias so that the built-in bias moves in a direction of (i.e., towards) the desired built-in bias. In other embodiments, the temperature of the at least a portion of the ferroelectric layer of the media is elevated to thereby tune the built-in bias so that the built-in bias moves in a direction of (i.e., towards) the desired built-in bias. The desired built-in bias can be a zero built-in bias, or a non-zero built-in bias.
