Stress intensity factor for specimens was computed with ABAQUS program. Stress intensity factor was found to increase with increasing specimen diameter for a fixed span/radius ratio. Stress intensity factor decreased with increasing specimen height. Changing span was found to have no significant effect on fracture toughness of andesite. Fracture toughness was significantly lower for specimens with smaller height. The suggested testing height interval for this type of specimens was between height/diameter ratios of 0.49 &ndash
0.64. Results were compared to the results obtained by a well-known specimen geometry named semi-circular bend specimens (SCB) under three-point bending. SCB tests produced lower values for fracture toughness for both rock types. Fracture toughness was 0.99 MPa&

An innovative magnetic module which is concurrently capable of performing as an actuator and a sensor is proposed and illustrated. The magnetic module is basically similar to a micro-scale solenoid coil which is employed to actively adjust the height of a seismic rotating disc used in a gyroscope so that the induced pitch angle by Coriolis effect, purely due to exerted angular excitation, can be accurately measured. That is, the micro-magnetic module acts like an actuator for height regulation on the seismic rotating disc by applying appropriate electric current to the primary coil of the Micro-Magnetic Height Adjuster (MMHA). On the other hand, the secondary coil pair of the MMHA acts as a sensor which can detect the gap change between the seismic rotating disc doped by metal material, and the micro-magnetic module.

This research addresses the problem of the read/write head fly height control in a computer hard disk drive. The computer hard disk read/write head flies above the disk at a very small distance in order to pick up small magnetization changes on the recording surface. The distance between the head and the disk thus determines the available recording density of the media. Modern computer disk drive achieves minimum fly height by using the air-bearing technology without feedback control. The air- bearing is able to maintain the read/write head at a sub-micron distance above the disk surface. As the need for storage capacity increases, it is necessary to futher reduce the fly height, and certain form of feedback control becomes necessary. In this research, we develop a mean to measure the read/write head fly height in a commercially available hard disk drive. In order to perform controller design, we also develop a system model that includes both the slider dynamics and the air- bearing squeeze effect. The popular $H_\infty$ optimization procedure is then used for controller synthesis. Experimental results on the fly height measurement and simulation results on the fly height control confirm the feasibility of the approach.

The present objective of the research is to get the high density recording system. However, a higher recording density requires smaller head-disk spacing, and therefore lowering-flying heads and smoother disk surfaces are needed. Due to the lowered fly height of the slider, glide avalanche requirements of the disks are consequently being tightened while the stiction requirement remain unchanged. In this article, the limitations of padded slider to meet stiction requirement on low glide height media tribology issue were investigate. In order to meet the glide avalanche requirement, to change the laser energy and its size of the laser texturing machine to get a concaved laser bump geometry, it can be seen that such design can get lower glide height but higher stiction. Therefore , to get the optimal design of such head/disk interface to get lower stiction is necessary. In the research, we observed that smaller bump spacing, bigger bump diameter, lower concave depth and fewer lubricant apply can reduce the contact area and meniscus of the head/disk interface, and exhibits better CSS performance in the test. In terms of the stiction model, it can be seen that more uniform asperity height distribution and lower lubricant tensor can get lower stiction force., Hence the better understood CSS technology is expected to be further extended into future high-performance disk drives.
