General NotesNote
The Commodore 1530 (C2N) Datasette, later also Datassette (a portmanteau of data and cassette), is Commodore's dedicated magnetic-tape data storage device. Using compact cassettes as the storage medium, it provides inexpensive storage to Commodore's 8-bit computers, including the PET, VIC-20, and Commodore 64.
The Datasette is probably the most sophisticated tape-storage method of any microcomputer. Typical compact cassette interfaces of the late 1970s use a small controller in the computer to convert digital data to and from analog audio tones.
In the Datasette, instead of writing two tones to tape to indicate bits, patterns of square waves are used, including a parity bit. Programs are written twice to tape for error correction; if an error is detected when reading the first recording, the computer corrects it with data from the second.Note Type
