Bytes to 2200 Software Tracks Calculator
Given a number of bytes of the industry-standard 8-bit variety,
this will calculate the approximate number of 1792-word 2200
software tracks. This is useful when evaluating disk space because
non-2200 people usually quote in bytes.
- We use KB, MB, GB and TB here to mean thousands, millions, billions and
trillions, rather than 2**10, 2**20, 2**30 and 2**40, respectively.
- Because the 2200 has 9-bit bytes, the number of 2200 tracks needed to store
non-2200 data can vary slightly depending on whether the data is ASCII or
- We take no notice of wasted space than can occur on a disk system because it
was designed for 8-bit bytes. For example, sometimes a 512-byte (4,096-bit)
physical disk record is used to hold 112 words (4,032 bits) of 2200 data,
thereby 'wasting' 64 bits per physical record.
