    Abstract: A seek-scan probe (SSP) memory involves multiple-wafer bonding needing precision small gaps in between. Solder reflow bonding is typically used to join the wafers due to its reliability and ability to hermetically seal. However, solder reflow bonding may not provide a consistently controllable gap due to flowing solder during the bonding process. Thus, a bond stop technique and process is used to provide accurate cantilever to media gap control.

    Abstract: The presently disclosed technology teaches an improved voltage pattern for conductive tips utilized as moveable top electrodes for writing data bits into ferroelectric media. A conductive tip is dragged in contact or near contact with a ferroelectric surface forming a moveable top electrode on a ferroelectric media disk. A metallic film is deposited onto a bottom-side of the ferroelectric media forming a conductive bottom electrode. Applying electrical voltage pulses between the conductive tip and the bottom electrode induces polarization switching of the ferroelectric media under the head. The improved voltage pattern incorporates positive and negative overshoot voltages to induce a polarization switch in the ferroelectric media and positive and negative drag voltages to expand a polarized region on the ferroelectric media. Potential benefits of the improved voltage pattern include reduced cross-track blooming and reduced along-track blooming resulting in a more uniform track width and bit series length.

    Abstract: An information storage device comprises a media including a ferroelectric layer and a conductive layer and a cantilever adapted to be actuated toward the media. A tip extends from the cantilever and an electrode associated with the cantilever. When the cantilever is actuated, the tip applies a contact force to strain the media so that a charge is coupled from the ferroelectric layer to the tip. A signal is applied to the electrode to generate electrostatic force between the electrode and the conductive layer, causing the cantilever to vibrate based on a frequency of the signal. Vibration of the cantilever causes the contact force applied by the tip to the media to vary. Polarization of the ferroelectric layer can be determined based on one or both of a baseband signal generated by the charge accumulated at the tip and an upper-band signal generated by the variation in phase of the charge accumulated at the tip.

  • Publication number: 20090059773
    Abstract: An electron beam recording apparatus is disclosed that records information onto the surface of a sample by using an electron beam. The electron beam recording apparatus includes an electron source that irradiates the electron beam, a magnetic detector that is configured to move onto and out of an irradiation axis and acquires magnetic information on the irradiation axis, a convergence position control part that calculates a convergence position correction amount for correcting a convergence position of the electron beam with respect to the surface of the sample based on the magnetic information, and a convergence position adjusting part that adjusts the convergence position of the electron beam with respect to the surface of the sample. The convergence position control part causes the convergence position adjusting part to adjust the convergence position of the electron beam with respect to the surface of the sample based on the convergence position correction amount.

  • Publication number: 20080316906
    Abstract: A transducer for a storage medium has a supporting element positioned over the storage medium with a first head configured to interact with the storage medium and a second head operatively connected to the first head to interact with the storage medium. The second head is carried by the supporting element in a position adjacent to the first head, and the first head and the second head are aligned in a scanning direction. The first head performs the reading of a data item stored in a portion of the storage medium, the reading entailing the deletion of the data item, and the second head performs the rewriting of the data item in the same portion of the storage medium.

  • Publication number: 20080316904
    Abstract: The present invention relates to a method of reducing the wear of a tip of a probe when the tip is in contact with a surface of a substrate and when the probe is mounted on a support structure. A method is provided where a load force is applied to the probe, thereby causing the tip to be maintained substantially in contact with the substrate surface and a modulation step where the e magnitude of the load force is modulated at a modulation frequency. The modulation frequency is selected to be greater than a fundamental vibration frequency of the support structure on which the probe is mounted.

  • Publication number: 20080316905
    Abstract: A storage device including a storage medium for storing data in the form of topographic or magnetic marks. At least one probe is mounted on a common frame, the common frame and the storage medium designed for moving relative to each other for creating or detecting said marks. Each probe includes a tip facing the storage medium, a read sensing element, a write element and a capacitive platform, that forms a first electrode and is designed for a voltage potential applied to it independent from a control signal for said read sensing element and for said voltage potential applied to said capacitive platform being independent from a control signal for said write heating element. It further comprises a second electrode arranged in a fixed position relative to the storage medium forming a first capacitor together wherein said first electrode and a medium between the first and second electrode.
