International Classification:

G11B 21/02

US Classification:

360 75, 360 60, 360 71

Abstract:

Secure data is written to a disk during manufacture in such a way that it can be read but not copied. Methods include writing triangular transitions or very slow transitions from positive magnetic to negative magnetic and then erasing the negative parts to yield a code that consists of positive read back amplitudes only. Or, high frequency transitions can be written during servo writing.

Abstract:

A method and apparatus for computer modeling the production process is disclosed. An integrated product and process engineering system may be a computer modeling system that models both a generic production process and a specific individual production process. The integrated product and process engineering system may store a time dependent process parameter related to the production process, having uploaded them via an interface. The time dependent process parameters may be retrieve and displayed to the user on a display using a remote function call enabled function module. The time dependent process parameters may be uploaded from an external system or revised using a remote function call enabled function module.

US Classification:

703 2

Abstract:

A method and apparatus for computer modeling the production process is disclosed. An integrated product and process engineering system may be a computer modeling system that models both a generic production process and a specific individual production process. The integrated product and process engineering system may store a time dependent process parameter related to the specific product design and organize the time dependent process parameters by product variants. The time dependent process parameter may have a parameter value and a start time. The time dependent process parameters may be input/output component consumption parameters, activity duration parameters, resource capacity consumption parameters, and activity scrap parameters.

Abstract:

A method and apparatus for computer modeling the production process is disclosed. An integrated product and process engineering system may be a computer modeling system that models both a generic production process and a specific individual production process. The integrated product and process engineering system may store one or more time dependent process parameters related to the production process and one or more engineering change numbers related to different product designs. The effective time periods of the time dependent process parameters may be compared with the effective time periods of the engineering change numbers. Various flags may be associated with each comparison to indicate the validity of the time dependent process parameter.

International Classification:

G11B 19/04
G11B 5/09

US Classification:

360 60, 360 48

Abstract:

A data storage apparatus includes a data storage medium, a write element, a non-volatile cache memory circuit, and a controller circuit. The controller circuit is configured to record data on the data storage medium in groups of overlapping tracks using the write element. The controller circuit is configured to store a shingle block of data from a subset of the overlapping tracks in the non-volatile cache memory circuit, while at least a portion of the data in the shingle block of data is updated.

US Classification:

360 75, 360 25, 360 69

Abstract:

A hard disk drive (HDD) including a first resistive temperature detector (RTD) configured to detect a temperature generated by proximity of a slider and a media. The first RTD is proximate an air bearing surface (ABS) of the slider. The HDD also includes a second RTD configured to detect at least one temperature correlated to a fly-height of the slider. The second RTD is not required to be proximate the ABS of the slider. HDD also includes a read/write integrated circuit (IC) configured to determine the fly-height of the slider based on detection of temperatures by the first RTD and the second RTD.

Inventors:

Martin Chen - San Jose CA, US
Fu-Ying Huang - San Jose CA, US

International Classification:

G06F 13/38

US Classification:

710062000

Abstract:

A personal portable storage device (PPSD). The PPSD has a storage medium. The PPSD also includes a wireless component, coupled to the storage medium. Additionally, the PPSD includes transfer management electronics, coupled to the storage medium, which allow a host device to access the PPSD through the wireless component without requiring physical connections between the PPSD and the host device. The PPSD includes a self-contained energy source, coupled to the transfer management electronics. The PPSD also has a housing, which at least partially encloses the storage medium, the wireless component, the energy source, and the transfer management electronics, and is of a size and shape well-suited to being carried on a person, so that the PPSD is easy to transport.
