RISSlider Vibration Analysis at Contact Using Time-Frequency Analysis and Wavelet Transforms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Time-frequency analysis and wavelet transforms are employed to investigate transient contact dynamics at the head/disk interface of computer hard drives. Wavelet transforms are used to resolve ...
Numerical and Experimental Investigations of the Head/Tape Interface in a Digital Linear Tape Drive
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Finite element analysis is applied to simulate the head/tape interface in a Digital Linear Tape (DLT) drive. The numerical model was verified by contact spacing measurements using a “three-bump” ...
Measurement and Sources of Lateral Tape Motion: A Review
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The sources of lateral tape motion in a tape drive are reviewed. Currently used measurement methods and models for lateral tape motion are analyzed and compared. The effect of roller run-out, ...
Lateral Motion of an Axially Moving Tape on a Cylindrical Guide Surface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The lateral motion of a tape moving axially over a cylindrical guide surface is investigated. The effects of lateral bending stiffness and friction force are studied and the attenuation of ...
Characterization of Tape Edge Contact Force With Acoustic Emission
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Acoustic emission sensors were used to detect contact between a moving tape and the flange of a tape guide. The influence of tape drive operating conditions on the tape edge contact force ...
An Investigation of Slider Vibrations in Near Contact Recording Using a Digital Laser Doppler Vibrometer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: At a flying height of 10 nanometers, contacts between slider and disk are likely to occur, and control of contact-induced slider vibrations is an important design consideration. In this study, ...
Effect of Intermolecular Forces on the Dynamic Response of a Slider
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A single-degree-of-freedom spring-mass-damper model has been developed to simulate the dynamic response of a typical magnetic recording slider under the effect of intermolecular forces. and (2003, ...
A New Finite-Element Based Suspension Model Including Displacement Limiters for Load/Unload Simulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new beam suspension model for load/unload simulations of magnetic hard disk drive sliders is presented. The model is applicable to the load/unload process as well as to the dynamic flying ...
The Use of System Identification Methods to Evaluate the Effects of Slider-Disk Contacts and Disk Micro-Waviness on the Flying Height Modulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: System identification methods have been used to study the response of a magnetic recording slider during contact with a scratch on the disk surface. In addition, the slider response was studied ...
Failure of Brittle and Ductile Hard Disks Due to High Shock Levels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The failure due to accidental drop of magnetic recording disks made of brittle or ductile materials is of great interest in the design of small form factor hard disk drives. In this study, ...
