The prerequisites for the fact that the “golden” discs are worse than the “aluminum” ones are laid down in the recording technology itself. Standards for compact discs provide that the reflection of the laser beam from bright areas should be at least 70%.
Such requirements are met for stamped discs. However, recordable discs, unlike stamped discs, have an additional recording layer of organic polymer. This layer has limited transparency. Therefore, standards for recordable discs allow that reflection from highlights should be at least 65%. Continue reading
“Stamped” discs (or, if you want, “aluminum”) can be made in various ways. The most common is, to be precise, injection molding, rather than stamping. Modern technologies make it possible to achieve extremely high manufacturing accuracy, however, compact discs made in this way will be prohibitively expensive. Therefore, really “stamped” discs contain many single, at least errors. The main thing is that the available number of errors does not cause a decrease in read speed. Continue reading
Recently, CD recorders have become very widespread. In this regard, the circle of people dissatisfied with these devices has also expanded dramatically. There was a firm belief that recording on “golden discs” is generally unreliable, “golden discs” cease to be read over time, and you will not find a good blank (“blank”) for recording during the day with fire. To deal with these issues, a series of tests were carried out in the research laboratory of the EPOS company. Continue reading
What are the models of Zip drives?
Currently, there are 2 main types of Zip drives: Zip-100 (100 MB removable disk capacity) and Zip-250 (250 MB removable disk capacity). Zip-100 is available in both external and internal versions. In external design, Zip-100 drives are available with SCSI, LPT and combined (Zip Plus) interfaces. A drive with a combined interface (Zip Plus) automatically recognizes the type of interface to which the drive is connected. Continue reading
