HD DVD Versus Blu-Ray Discover the Ultimate Winner TECH INSIGHT HD DVD veRSUS BLU-RAY HD DVD veRSUS BLU-RAY discOveR the ULtiMAte winneR Like the war between VHS and Betamax in the 1980’s, and the more recent conflict between DVD-RW and DVD+RW, another battle of competing video formats is now underway. Two new technologies, HD DVD (High Definition DVD) and Blu-ray, have stepped into the ring to compete for consumer acceptance. The rivals have several similarities, so you may find it difficult to pick a clear favourite at first glance. A detailed comparison of the two contenders, highlighting their strengths and weaknesses, will help you determine the ultimate winner.

  • Will Sonyâ•Žs Fourth Playstation Lead to a Second Sony V. Universal?
    WILL SONY’S FOURTH PLAYSTATION LEAD TO A SECOND SONY V. UNIVERSAL? † SETH ASCHER ABSTRACT Sony has included a “share” button on the next version of their popular PlayStation video game system. This feature is meant to allow players to record and share videos of their gameplay. This service shares similarities with the controversial “record” button that Sony included with its Betamax players over thirty years ago. The Betamax player was the subject of the landmark case Sony v. Universal, a foundational case for the modern application of copyright law to new technology. This Issue Brief examines how this “share” feature would fare under the framework laid out by Sony v. Universal and other evolutions in copyright law. INTRODUCTION On February 20, 2013, Sony announced their newest videogame system, predictably named the PlayStation 4.1 Chief among its new features is the share button displayed prominently on its controller.2 Microsoft’s newest offering also has a similar feature.3 Pressing the share button will allow a player to post images or videos of their gameplay to the internet, sharing them with their friends and complete strangers.4 The PlayStation 4 even buffers the last few minutes of gameplay so that a player can share their gameplay video after the fact.5 Sony’s intention is to provide an easy way for players to share images and videos online.

  • Simultaneous Intensity Profiling of Multiple Laser Beams Using the Bladecam-XHR Camera
    Simultaneous Intensity Profiling of Multiple Laser Beams Using the BladeCam-XHR Camera Shaun Pacheco College of Optical Sciences, University of Arizona Rongguang Liang College of Optical Sciences, University of Arizona Rocco Dragone Vice President of Engineering, DataRay, Inc. Real-Time Profiling of Multiple Laser Beams There are several applications where the parallel processing of multiple beams can significantly decrease the overall time needed for the process. Intensity profile measurements that can characterize each of those beams can lead to improvements in that application. If each beam had to be characterized individually, the process would be very time consuming, especially for large numbers of beams. This white paper describes how the BladeCam-XHR can be used to simultaneously measure the intensity profile measurements for multiple beams by measuring the diffraction pattern from a diffraction grating and the intensity profile from a 3x3 fiber array focused using a 0.5 NA objective. Diffraction Gratings Diffraction gratings are periodic optical components that diffract an incident beam into several outgoing beams. The grating profile determines both the angle of the diffracted beam modes and the efficiency of light sent into each of those modes. Grating fabrication errors or a change in the incident wavelength can significantly change the performance of a diffraction grating. The BladeCam- XHR, Figure 1, can be used to measure the point spread function (PSF) of each mode, the relative efficiency of each mode and the spacing between diffraction modes. Figure 1 BladeCam-XHR Using the BladeCam-XHR for Diffraction Grating Evaluation The profiling mode in the DataRay software can be used to evaluate the performance of a diffraction grating.

  • CD-ROM, CD-R, CD-RW, and DVD-ROM Drives) Are the Hardware Devices That Read Computer Data from Disks
    A Brief History of CD/DVD The first disc that could be written and read by optical means (using light as a medium) was developed by James T. Russell. In the late 1960s, Russell created a system that recorded, stored, and played audio/video data using light rather than the traditional contact methods, which could easily damage the disks during playback. Russell developed a photosensitive disc that stored data as 1 micron-wide dots of light and dark. The dots were read by a laser, converted to an electrical signal, and then to audio or visual display for playback. Russell's own company manufactured the first disc player in 1980, although the technology never reached the marketplace until Philips and Sony developed the technology. In late 1982, Philips and Sony released the first of the compact disc (CD) formats, which they then called CD-DA (digital audio). In the years since, format has followed format as the original companies and other industry members developed more adaptations of the original specifications. Digital Versatile disc (DVD) had its beginning in 1994, when two formats, Super disc (SD) and Multimedia CD (MMCD) were introduced. Promoters of the competing technologies failed to reach an agreement on a single standard until 1996, when DVD was selected as a convergence format. DVD has, in the few years since, grown to include variations that do anything that CD does, and more efficiently. Standardization and compatibility issues aside, DVD is well-placed to supplant CD. Magnetic vs Optical Media Optical media are storage media that hold information in digital form and that are written and read by a laser; these media include all the various CD and DVD variations, as well as optical jukeboxes and autochangers.

  • Injection Locking of New Focus Lasers for 100+ Mw of Power at 461 Nm
    TECHNICAL APPLICATION NOTE Injection Locking of New Focus Lasers for 100+ mW of Power at 461 nm 1. Introduction The GaN blue light-emitting diode, first demonstrated by Akasaki, Amano, and independently by Nakamura earned them the Nobel Prize in Physics in 2014 and has revolutionized modern lighting technology. This led to many new developments, one of which was the blue laser diode which has similarly transformed the way researchers obtain laser light at blue wavelengths. The blue laser diode has also greatly reduced the cost and level of complexity involved with such experiments. The blue laser diode can be integrated into an external cavity with wavelength-selective optics to make a tunable external cavity diode laser (ECDL). One example of this is the New Focus TLB-6802 Vortex™ Plus tunable Figure 1.
