What is worse than the “golden” wheels?

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

SPD EEPROM: Functioning Algorithm

With the advent of the new SDRAM standard, a new I2C interface has also appeared. The interface was developed by Philips and is used as an internal auxiliary bus of the motherboard for exchanging information with non-volatile memory SPD-EEPROM (installed on the PCB SDRAM), which is responsible for identifying the components installed on the module. The bus is characterized by extreme ease of implementation – 2 signal lines, the transmission or reception of information on which is carried out programmatically. Continue reading
