Optical Storage Devices • An optical disk is a high-capacity storage medium. An optical drive uses reflected light to read data. • To store data‚ the disk’s metal surface is covered with tiny dents (pits) and flat spots (lands)‚ which cause light to be reflected differently. • When an optical drive shines light into a pit‚ the light cannot be reflected back. This represents a bit value of 0 (off). A land reflects light back to its source‚ Representing a bit value of 1 (on)

Distortion. If I could put that moment into one word that would be it. Everything in my mind was racing‚ as if my thoughts were on a high speed merry go round that was no longer full of merriment‚ but filled with a feeling of disaster. Drowning in a vast sea of uncertainty‚ the light shining from above was slowly vanishing from sight. I no longer had hope. I remember just wanting to sleep. To drift away and have all my pain and worries leave my body. I never wanted to wake up and feel the agony

Fabrication is more powerful truth‚ at least in the eyes of Hollywood When it comes to film’s interpretation of history and reality‚ such as the recent film’s “Argo” and “Zero Dark Thirty”‚ Hollywood has long had a habit of altering facts‚ creating illusions and fabrications‚ and even distorting final outcomes. Hollywood is an industry‚ and for a long time now‚ has understandably aimed at creating the best possible plot line with regard to its films. In some ways‚ it could be considered a “dream

WHAT IS THE PRINCIPLES OF OPTICAL DEVICES‚NAME AND EXPLAIN FEW ! ANS:Storage and retrieval of data on optical disks can be described in two simple steps. First‚ data marks are recorded on a surface. Data marks can be prerecorded‚ like on a music CD‚ or they can be recorded by users on blank disks‚ like with CD-recordable products. The second step is retrieval of information from the disk‚ where a light beam scans the surface. Modulation in the reflected light is used to detect the data-mark

(p. 197) The heavily edited nature of these types of reality shows is a key contribution to the distortion of certain social constructs and the perpetuation of common stereotypes. For example‚ in order to create a particular type of character‚ such as a vain and dispassionate female contestant‚ the editors may choose to only show the video clips of that

Mie resonances in dielectric particles can increase the local optical density of states (LDOS) associated with either electric or magnetic transition rates in nearby quantum emitters without ohmic losses. Their rather large quality factors compensate their low field confinement as compared to the plasmon resonances of metallic nanostructures for which nonradiative decay channels dominate. We show theoretically that near-infrared quadrupolar magnetic resonances in silicon particles can preferentially

Not ones average Pitch High pitch distortion perception‚ it’s something not many people know about yet experience every day. I made a couple pitch distortion tests I found in the internet‚ the topic was entertaining and the best thing about it is I did not know one thing about the topic when I chose it. Everything about this topic is new to me and to be honest‚ I was scared about this project because I did not know what it was about. It was fun learning about pitch perception because I experience

What Causes Optical Illusions? Optical illusions are how the eye sees the illusion. Most people now believe that seeing optical illusions has to do with perspective‚ or the way you look at something. The concept of optical illusion was first used by the Greeks. They built their temples so that the roof was slanted. This gave the illusion that the temple was actually standing straight. We get used to how things are supposed to be‚ and sometimes our brain gets the wrong message. Our brain puts
