From the Floppy Diskettes


Q: Average Signal Amplitude?

A: American National Standards Institute.



A: Bits per radian.


Q: Extra Bit?

A: An extra bit occurs whenever a pulse is detected during a read attempt over a track that has previously been DC erased with a current equivalent to the quiescent value of the Test Recording Current. To be considered an extra bit, the peak amplitude of this pulse must be greater than 20% of the average base-to-peak 2f signal level from that track when recorded with the Test Recording Current.


Q: Missing Bit?

A: A missing it occurs whenever the base-to-peak voltage amplitude of any flux transition is not at least 45% of the average base-to-peak signal level of the track under test, where2f is the Test Recording Frequency and the Test Recording Current is use.


From the Discs



A: International Standard Recording Code, which is an optional 12-character descriptor that identifies a specific track on an audio CD. Each track can have its own unique ISRC consisting of 2 alphanumeric characters (country), 3 alphanumeric characters (owner), 2 digits (year of recording) and 5 digits (serial number).

Q: Printable discs?

A: Discs can be printed directly by inkjet or thermal CD/DVD printers. There are 3 types of printable discs,

(1)   Ordinary silver reflecting surface discs.

(2)   Inkjet printable discs.

(3)   Thermal printable discs.


Q: Thermal printable discs?

A: Thermal printer can print by using thermal heat against the monochrome (single black, blue, or red colour) or CMY (blended colours) ribbons directly to above type (1) & (3) discs. Type (1) discs are to be coated by a special printable layer of lacquer whereas the type (3) is coated by either a white/cream/matt colour printable paint. This is common for using scanning equipment for reading the bar-codes or other index information on the printed discs. Most of the professional fulfillment, software houses or turnkey operators are using this type discs to do the printing-on-demand jobs. The printed discs are long lasting and resistant to hazardous environments, like water, heat, humidity, magnetism etc.



Q: Inkjet printable discs?

A: Inkjet printer always provide a higher pixels of picture-like printing. This type of discs are to be coated by a special paint, normally white or cream, to absorb the ink printed by the inkjet printer. There are some setbacks, this discs are to be made by order due to the expensive paint, and the background ink will turn yellow or withered away condition after some time, the quicker will be 6 months. That will also affected those printed or non-printed discs.


Q: Speeds of discs?

A: There are 2 essential speeds for each recordable optical discs, no matter it is a CD-R, CD-RW, DVD-R and DVD-RW, the reading and the recording speeds.


Q: Multi-speed?

A: This will refer to multi-read and multi-write speeds.


Q: What is an audio CD.

A: The disc compiled with songs and created according to The Industry standard (Red Book)
