Track capacity Track capacity is the maximum capacity achievable when there is one
physical data record per track formatted without a key. Because the
track can contain multiple data records, additional Address Markers,
Count Areas, and gaps reduce the number of bytes available for data.
The track capacity is the number of bytes left for data records after
subtracting the bytes needed for the home address, record zero,
address marker, count area, cyclic check (for error correction), and the
gaps for one data record.
For 3390 emulations, the track capacity is 56,664 bytes. For 3380
emulations, the track capacity is 47,476 bytes.
