Hard disk drive multimedia

The Electronic Library, 1993
A multimedia effect can be provided by programs which use the hard disk drives of PCs. Knowledge Adventure and Science Adventure are two programs providing a multimedia experience without the use of CDROM. Knowledge Adventure provides information on general subjects while Science Adventure concentrates on science material with text taken from a book by

Magnetic Hard Disk Drive Form Factor Evolution

[1993] Digests of International Magnetics Conference, 1993
The trend toward smaller form factor in the magnetic disk storage industry is analyzed and discussed. Miniaturization is the result of small systems' storage requirements and advances in magnetic recording technology. This has led to the creation of a scaling methodology for determining disk drive sizes. The authors describe the scaling methodology and

Thermal Modeling of Hard Disk Drives

7th International Symposium on Information Storage and Processing Systems, 1996
Abstract A methodology for thermal modeling of hard disk drives (HDD) using a computational fluid dynamics (CFD) program that solves the conjugate (conduction and convection) heat transfer problem is presented. The methodology addresses assumptions, model construction, and boundary conditions, as well as measurement methods for ...

Hard disk drives for spacecraft application

57th International Astronautical Congress, 2006
Accurate resolution imaging from Satellites involves large amounts of data that has to be stored on board the spacecraft computer. The data can be stored on Hard Disc Drives. However survival to the mechanical environment existing during the spacecraft launch and to the space environment during satellite operations are two major challenges in the use ...

MEMS Applications in Hard Disk Drives

TRANSDUCERS 2007 - 2007 International Solid-State Sensors, Actuators and Microsystems Conference, 2007
As a new application of MEMS to hard disk drives, gimbal-chip (a MEMS chip that replaces suspension's gimbal function) was investigated. A micro-actuator for tracking servo was also integrated in the chip. Design, process, and performance of the chip are reported.

Hard disk drive suspension interconnect modeling

IEEE Transactions on Magnetics, 2002
As hard disk drive write and read data rates become higher, careful modeling of suspension interconnects becomes more important to understanding and designing the write and read circuits. In the past, interconnect models have often ignored losses and included only one propagation mode. More complete models that avoid these limitations are reviewed here

Future trends in hard disk drives

IEEE Transactions on Magnetics, 1996
Magnetic hard disk drives have significantly improved in size, performance and cost due to many technological innovations; including magnetoresistive heads, low noise thin film disks, PRML channels and advanced mechanical actuators and motors. By analyzing specification trends of each new disk drive design, a perspective of this evolution can be ...

Uncertainty modeling for hard disk drives

2014 American Control Conference, 2014
A modern hard disk drive uses a dual-stage actuator to read/write data on a track with width less than 100nm. The dual-stage actuator requires an advanced controller to achieve high performance on millions of hard disk drives. This paper presents a numerical algorithm utilizing convex optimization to create an uncertainty model, for the purpose of ...

Operational Shock Response of Ultrathin Hard Disk Drives

2014 Conference on Information Storage and Processing Systems, 2014
Operational shock is one of key challenges for designing the ultrathin mobile hard disk drives (HDDs) due to the reduced thickness of mechanical components and their stiffness. Some simplifications in the conventional methods for operational shock simulation are not valid. In this paper, a method for system level modelling and simulation of operational

Head–disk contact detection in the hard-disk drives

Wear, 2003
Abstract The increasing capacity of current hard-disk drives places a great importance on reliability, as tens of gigabytes of data can be lost in an instant due to a single tribological failure event. To improve the reliability of the head–disk interface there is a need to predict, measure and monitor any interactions during manufacture. This paper
