Karim Kaddeche has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20190341077
    Abstract: The invention generally relates to hard disk drives with a disk and a read/write head, and methods for preventing contact between the disk and the read/write head. The hard disk drive includes a z-axis actuator configured to control movement of the read/write head, and to prevent contact between the read/write head and the disk, based on signals from a controller that indicate when the distance between the read/write head and the disk are outside a predetermined range, such as between 0 and 10.0 nm.

  • Patent number: 9881644
    Abstract: The invention generally relates to a hard disk drive with a disk, a read/write head, a z-axis actuator, and a controller. A surface of the disk and/or the head can be bare and thus devoid of any overcoat or lubricant layer, or alternatively the disk surface can have one or more layers with a combined thickness of less than 4 nanometers and the head can have a layer with a thickness of less than 2 nanometers. The hard disk drive can be enclosed, and its enclosed space can be a low pressure environment such as a near-zero or a zero pressure environment.

  • Publication number: 20170236542
    Abstract: The invention generally relates to a system for achieving reduced head-media spacing (HMS) in a hard disk drive (HDD) by providing active control over the positioning of a read/write head relative to a rotating magnetic data recording and reading surface of a disk. The system is configured to monitor and adjust positioning of the read/write head in real, or near-real time during disk rotation to maintain the HMS between a magnetic transducer of the read/write head and the disk surface within a defined range, generally between 1.0 nm and 10.0 nm, and, in some embodiments, approximately 4.3 nm. The system replaces the conventional an air bearing surface (ABS) design with a fully active suspension to maintain the head flying height within the desired range. The system further allows for each of the magnetic transducer and disk surface to be to be devoid of any overcoat or lubricant layers.

  • Patent number: 9721600
    Abstract: Rotational latency is reduced in a standard conventional form factor HDD system by replacing, for example, the prior art rotary arm actuator of a conventional HDD, with one or more belts and pulleys and one or more read/write heads mounted on, or otherwise associated with the belts. Multiple scaled iterations facilitate energy savings and power optimized systems, without compromise to data access performance.
