I. Introduction Video cassette recorders based on magnetic recording technology have become very common throughout the industrial world. Recent efforts have been directed toward improving the reliability of VCR's. These efforts have shown that the reliability of VCR's is closely related to head wear and contamination. Although the importance of head wear and head clogging is well known[',21, few experimental studies have addressed the relationship between head wear and head contamination. In this paper we have investigated the location of deposits on the head surface and the development of the wear scar. We have used the \"micro indentation technique\" in conjunction with Atomic Force Microscopy to determine the wear rate and contact pressure over the head as a function of position and time.","PeriodicalId":127085,"journal":{"name":"1997 International Conference on Consumer Electronics","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124333611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

I t presents the principles of the combined video signal (TV) and sound signal (W and radio) demodulation using PLL techniques. This novel front-end demonstrates that FM radio and television I reception can be successfilly merged into one module , resulting in applications with reduced size and lower cost. INTRODUCTION tion, gain control, demodulation, switching, limiting and two PLLs are implemented on a single chip in an SSOP28 or SSOP20 package. The high level of integration achieved with the new advanced circuit design has resulted in a dramatic reduction of IC pin count, peripheral components, and factory alignments. On-chip functions of the IC (Fig.1) include: A vision IF (VIF) section with PLL for true synchronous demodulation of the video modulated IF signal A sound IF (SIF) section for QSS signal processing, together with an AM demodulator for the AM sound and a PLL for demodulating the FM sound IF signals Additional stages for FM radio detection which are combined with the TV sound IF circuit. This paper describes a novel RF concept which is capable of receiving both broadcast television and FM radio signals, and is intended for applications in desktop personal computers. Compared to solutions using separate-radio and TV tuners, the module allows for a considerable reduction in total cost and board space. The cost saving is achieved by sharing key components and other circuitry needed for channel selection and demodulation of broadcast television and FM radio.

Receiving FM radio with a television tuner has been demonstrated before, but always with mediocre performance. In this respect the novel TV/FM front-end can be considered a breakthrough; the quality of the FM audio delivered is more than adequate, and competes with that of * an average Mini HiFi system and or separate radio modules available on the market. A novel feature of the RF module design is a new IC2 with circuitry for both radio and television demodulation.
