DE2907987A1 - Multipurpose audio or video cassette system - allows two cassettes or tapes to be inserted simultaneously or consecutively for copying or endless playing - Google Patents

Abstract

The cassette tape system is suitable for all cassette and tape systems as an endless recording system and as a tape copying procedure. Two cassettes or tapes can be placed one after another and simultaneously into the recorder. The recorder has duplicate sound or video heads. Copying can be accomplished on the same recorder, i.e. there is no need to connect additional devices e.g. another tape recorder.

Description

Title Casetten-Band-System-Ovi (Abbreviation: C-B-S-O)

Areas of application: The C-B-S-O is used wherever it depends on 1. wanting to record over an unlimited period of time, especially for Don, film, data processing and video recording devices, 2. already: to duplicate existing recordings.

Weck: 1. For longer recordings it is necessary to use tape length-related Remove time limits, 2. a second device of the same type is no longer required.

State of the art: According to the current state of the art, 1. All Tapes limited to a certain time.

2. Is a second machine of the same type required for copying?

Criticism of the state of the art: 1. To date it is not possible to keep records to be carried out in the endless belt process.

2. A second device is required to duplicate a recording.

Exercise: The C - S-O allows: 1. Recordings using the Fudlos method, 2. Duplicate existing records Insdng: These tasks are according to the invention achieved in that the recording device simultaneously and one after the other can be loaded with two dasettes or ribbons (e.g. using the drawer method - on top of each other or next to each other, standing or lying).

For this purpose, the recording device should expediently be doubled Number of heads (for sound recordings) or

Video heads (for video recordings) or prisms and lenses (for film cameras) etc., be equipped as before, Switching from Casette resp. Tape can now be carried out as follows: 1. For new recordings: a) with an exactly working length measuring device the remaining tape length is determined, and If there is a remaining tape length to be determined, the device switches to the second Tape around, whereby the same recordings can come about for a short time, to the exact later one Enable cutting; b) j each commercially available tape receives in addition to the existing one Blank piece of tape a mark that is recognized by the tape recorder, which means that the recording is switched from tape 1 to tape 2, whereby it remains the same for a short time Recordings can come to enable exact cutting later.

2. When duplicating: By a circuit between the reproduction part and the second recording system part, duplication is possible.

The technical arrangement is left to the user of the invention; accordingly, Section 1 (4) of the minimum provisions for patents in the version dated 3C. July 63.

Achievable advantages: The advantages that can be achieved with the invention are: 1. Recordings in the endless process are possible.

2. Recordings that have been created once can save costs, i.e. without Can be duplicated using a second device of the same type.

3. The development of the tapes can be based on pure quality improvement restrict.

Description of possible applications: The following can benefit from the C-B-S-C: 1.% on recordings, 2. video recordings, 3, film recordings, 4. data processing systems

Claims (2)

Claims: Generic term: Casetten-Band-System-Ovi (C-B-S-O), suitable for all cassette and tape systems 1. as an endless recording system, 2. as Duplication process. Characteristic 1. characterized in that two cassettes or Ending parts: Tapes simultaneously and one after the other in the recording device can be inserted. 2. characterized in that the reproduction with the recording device takes place without connecting an additional device.
