Initial Monogram Tattoos

Storage / 1

I decided to use magnetic tapes "real" (even simulated floppy ... that idea of \u200b\u200b"V-TAPE) as audio-cassettes, open-reel 1 / 4 and VHS. Disks (floppies possibly) come later.

In a previous article entitled Use of Storage in Heritage / 1 explained my ideas about using tape on a "Batch Processing" (see also: Real Tapes ). But now I want to explore nature and the "flavor" of the tape itself in the context of this project.

There is a wide range of applications, each of which has its own requirements regarding the use of magnetic tapes.

A database application, for example, requires large files, and of increasing length, a common operation is to add records at the end of the tape (append) from there it is undesirable to host more than one file on each tape. In this case the program does not even require the notion of "file" be content to have a "drive" which to read or dump data as "streams."

Not so with the programs, as these are fixed length and usually small compared to the capacity of the tape. The programs must be established as in files, with several (possibly many) of them on one tape.

A third case are the configuration files and programs start, use small files and isolate whose natural habitat would be punched tape ... if it possible for Heritage / 1.

specific peripherals that I have designed so far are Next:

a) Video tape (VHS)
b) Audio 1 / 4 open-reel
c) Audio-Cassette

The VHS is better suited for databases for high capacity, faster access and (mostly) better availability, for any database application will require more than one drive (at least four) operating simultaneously.

open-reel tape draws me to folk flavor (remember the tapes used on older computers) but its main limitation is the availability ... I can practically only have one of these machines. However, it is well suited for the job as transport can be controlled by program and their ability and performance are acceptable. Probably will use it to house programs, including the operating system itself.

The audio-cassette is extremely limited both by capacity and access speed (I believe, reliably, about 300 characters per second), and the great difficulty controlling their transportation from the program. However, I have reserved an honorable task: to replace the traditional paper punch tape.

A perforated tape is placed on the reader and read as a whole, from top to bottom. This differs from the magnetic tape which you play, rewind etc under the control of the program. Well, just that I do with the cassette: The program is limited to read or write "all" as the operator (ie, me) handles the transport mechanism ... manually. In this connection, my audio-cassettera simulate both the reader and the punch tape.

short, my plan for the use of tapes is as follows:

a) VHS: Database files
b) Open-Reel Audio Programs (including OS)
c) Audio-Cassette: Bootsrap, config files, etc.

And it appears that none of this has come out of improvisation but many weeks giving back and up front the issue ...
