It’s the only "one-stop-shop" event in our industry that lets 6 attendees learn about new products and technologies, meet Alchemy and Rigorous with key suppliers, attend a world-class technical conference, Science: The Evolution of and hear from the leaders of the HDD industry. 60% of Hard Disk Drives attendees say they come to DISKCON to learn about new technologies, 48% to stay updated in data storage manufacturing techniques, and 29% attend because it improves their ability to do their job. Over 70% of attendees find it challenging or somewhat challenging to stay informed of new products and technologies 16 related to the HDD industry. Close to 90% of attendees feel that DISKCON USA does a Highlights from DISKCON good job of helping with that challenge. USA The Mark Geenen Technology for Youth Charity Golf Tournament raised almost $30,000 for Ronnie Lott’s All Stars Helping Kids charity. The money will go to Eastside Preparatory School in East Palo Alto. It is a huge boost for the school’s recent fund- raising drive. Thank you to all who participated; your generosity will make a tremendous 20 impact on the lives of many young people. Storage News For the first time ever at DISKCON USA, we offered a CEO Summit.

  • Competitive Strategy of Global Firms and Industrial Clusters1
    Competitive Strategy of Global Firms and Industrial Clusters 1 Case Study on the Hard Disk Drive (HDD) Industry Tomofumi Amano* 1. Introduction This report discusses the location strategies of multinational firms and the industrial policies of the countries that are the recipients of their investment. For firms engaged in international business, the timing of foreign investment, selection of locations, and maintenance and expansion of their local operations are all important strategic matters. Then what foreign investment strategies have been used by firms that have succeeded in strengthening their competitive advantage? What are the unique aspects of the policies taken by recipient countries? This report will focus upon the strategic nature of investment for global firms and the strategic nature of investment-attracting policy for the recipient countries. Because the determinant factors of foreign investment have been a core theme for studies on multinational firms, there is already a large literature upon the topic. However, much of it consists of studies that identify and classi- fy the location factors based on economic theories and empirical studies using cross-section or pooled data. While these studies indicate the general frame- work of multinational firms’ location selection, it is difficult to derive from them the strategic implications related to individual firms’ foreign investment. * An Associate Professor at the Faculty of Business Administration, Hosei University and a researcher of the Manufacturing Management Research Center, University of Tokyo. 1 This report is an expansion and revision of the content of Chapter 5 of the following book for the purpose of presentation at the GRIPS/MMRC Joint Symposium: Amano Tomofumi, Higashi Ajia No Kokusai Bungy To Nihon Kigy : Aratana Kigy Seich He No Tenb (East Asian Linkage and Japanese Firms: A New Perspective of Corporate Growth), Yuhikaku.

  • THE DISK DRIVE 50 YEARS of PROGRESS and TECHNOLOGY INNOVATION (THE ROAD to 2 BILLION DRIVES) Tom Coughlin*, Dennis Waid+ and Jim Porter++
    THE DISK DRIVE 50 YEARS OF PROGRESS AND TECHNOLOGY INNOVATION (THE ROAD TO 2 BILLION DRIVES) Tom Coughlin*, Dennis Waid+ and Jim Porter++ *Coughlin Associates + Peripheral Research Corporation ++ Disk/Trend OVERVIEW / HISTORY The hard magnetic digital disk drive as we know it today is used in all computer applications, in home appliances and PVR/DVR’s; in automobiles, cameras, medical applications. It is now pervasive in all segments of our society. The technology got its start in IBM’s San Jose laboratories in 1952, with innovators, such as Rey Johnson, Dr. Al Hoagland, Al Shugart, Bobby Smith, and others. The disk drive is unique in its history for overall cost reductions, while at the same time fostering rapid technology growth, and reaping amazing production ramps. Success in this industry has been associated with: • Device Size reduction • Ongoing and substantial cost reduction per MB • Dramatic Technology Increases • High Volume Production efficiencies. As a result of the above accomplishments the industry has grown from a volume of several thousand disk drives per year, in the 1950’s to over 260 Million drives per year in 2003. The first digital hard disk drive was the 24 inch IBM 350-1 which was announced in 1955, and began shipping in 1956. This drive housed 50 24-inch disks, had an access time of 600 milliseconds, and a capacity of 5.0 Megabytes. Table 1 compares the specs on the 350 with the most recent Seagate Barracuda 7200.7 disk drive of 2003. Table 1 Disk Drive Comparisons 1956 2003 Manufacturer IBM Seagate Model 350-1 7200.7 Capacity (MB) 4.4 MB 200 GB Disk Size 24 In.

  • A Hard Disk Drive( HDD )
    A hard disk drive ( HDD ), commonly referred to as a hard drive, hard disk or fixed disk drive,[1] is a non- volatile storage device which stores digitally encoded data on rapidly rotating platters with magnetic surfaces. Strictly speaking, "drive" refers to a device distinct from its medium, such as a tape drive and its tape, or a floppy disk drive and its floppy disk. Early HDDs had removable media; however, an HDD today is typically a sealed unit (except for a filtered vent hole to equalize air pressure) with fixed media.[2] A HDD is a rigid-disk drive, although it is probably never referred to as such. By way of comparison, a so-called "floppy" drive (more formally, a diskette drive) has a disc that is flexible. Originally, the term "hard" was temporary slang, substituting "hard" for "rigid", before these drives had an established and universally-agreed-upon name. Some time ago, IBM's internal company term for an HDD was "file". HDDs (introduced in 1956 as data storage for an IBM accounting computer[3]) were originally developed for use with general purpose computers; see History of hard disk drives. In the 21st century, applications for HDDs have expanded to include digital video recorders, digital audio players, personal digital assistants, digital cameras and video game consoles. In 2005 the first mobile phones to include HDDs were introduced by Samsung and Nokia.[4] The need for large-scale, reliable storage, independent of a particular device, led to the introduction of configurations such as RAID arrays, network attached storage (NAS) systems and storage area network (SAN) systems that provide efficient and reliable access to large volumes of data.
